Peter Nielsen: Designing A New Molecule of Life Life as we know it is far more complex than one can imagine. The smallest molecule in the human body can play a large role in determining the genetic outcome or the overall well being of a person. In Peter Nielsen’s “Designing a New Molecule of Life”, he speaks of a molecule that hopefully one day will create a scientific and medical breakthrough. In this essay you will read a summary of Peter Nielsen’s article and the research he has done with this molecule. Peter Nielson, along with many other scientists, have spent years creating and experimenting with a synthetic molecule called peptide nucleic acid (PNA). PNA is an artificial polymer that has many similarities to deoxyribonucleic acid (DNA) and ribonucleic acid (RNA). It has the same storing features as DNA and RNA while being built on a protein based backbone therefore making it sturdier and simpler than the sugar phosphate-backbone. The molecule was created in hopes of having an immediate affect by pursuing a drug that would target DNA’s composing specific genes, to either enhance or block the gene’s expression. This new drug would be in efforts to interfere with the production of disease producing proteins. Although this molecule has produced highly anticipated medical research, it has also lead to speculations of being the origins of life. In his years of research, Peter Nielsen and his colleagues wanted to achieve the ability of PNA recognizing double-stranded or duplex DNA having specific sequences and also be able to link to it creating a triple helix. The recognition in duplex DNA is far more challenging being that the atoms involved in the sequencing bases are already involved in hydrogen bonds connecting the two strands together and therefore making it unavailable to link to another molecule. Further into Nielsen’s research, an experiment…...

...New York Life Insurance Company began in 1845 when, after the foundation was laid for a new enterprise that would come to be known as the New York Life Insurance Company, Elected Secretary Lewis Benton purchased the first policy for $5,000. So began a legacy of security and a commitment to keeping promises reflected still today in our core values. That passion and commitment to protection has continued unabated for nearly two centuries — seeing the nation evolve and events take place affecting the lives of Americans: from the Civil War, to the Johnstown floods in 1889, to the 1929 stock market crash, to Hurricane Katrina in 2005, 9/11, and of course, the recent recession. New York Life Insurance Company is one of the largest mutual life insurance companies in United States, and one of the largest life insurers in the world, with about $287 billion in total assets under management. The company ranks No.71 on the 2011 Fortune 100 list, making it the highest privately held insurance company on that list. In 2007, NYLIC achieved the best possible ratings by the four independent rating companies (Standard & Poor's, AM Best, Moody's and Fitch). In June 2009, the same four rating companies reaffirmed New York Life's "superior" financial strength, which became a selling point in national TV ad campaigns that same year. The company is now one of only three life insurers to hold the highest ratings currently awarded to any life insurer by all four rating agencies (Moody's:......

During this reporting period, LLR inducted four new staff members who all completed LLR’s in-house training on the LLR, Health and Safety as well as File and Data Management training. Referrals over the few months have grown steadily with positive client engagement in groups, 1-2-1 counselling and 1-2-1 Recovery Plan Sessions. During this short period we have already observed an increasing number of SU’s being very committed to their recovery journey and we expect their commitment to be reflected in their continued growth and change. The staff and management team have also been very supportive and continue to provide us with regular group space ensuring group activities got underway. Although actual attendance numbers for the group have been relatively low at this early stage, those who......

New Way to Experience Life

...When I was waiting for my wonderful summer vacation last year, I suddenly saw a red and yellow poster posted at a narrow corner outside the corridor which is drew my attention. It was the information about going to Beijing internship for one month. I knew this is a good chance for me to experience a brand new life without my family. Under the keen competition, I could enhance my working experience in China. It would help me to improve Mandarin and become competitive in the future. I watched the TV in the airport for the Shenzhou 9 rocket launch when I was arrived in Beijing. This is an amazing moment that I can watch the long rocket launch in the capital of Beijing, a place where is politically aware. At the same time, I was the first time to feel proud to be one of the Chinese people. As the rocket means the national achievement for a country, I would feel that all people who surrounded by me do have a strong sense of identity. It shows a miracle in China again. In Beijing, it is shocking to see a mountain of people inside the MTR station every day. If you walk slowly, other people will use their invisible hand to push you to walk faster magically. When people want to get off in the next station, they are likely to ask a question, “Are you getting off in the next station?”. If no, he/she will then switch the place with you so the person can get off quickly. Also, I needed to take transportation nearly two hours to office. The colleagues told me that it is normal to take......

A New Chapter in Life

...Name Date Teacher Class TITLE When I think of my college search, I think of a lot of stress and a lot of time. It was a very stressful time in my life and put a lot of pressure on me to get into a good school. Education is the most important part of one’s life. Not everyone goes to college right after high school, and college is not intended for everyone. For example, some people decide to work right after high school rather than go straight into college. College is quite expensive, and some may even say it is hard. However, college is not a bad thing. It has many good qualities. For instance, college is a time where students can venture out and meet new people. I knew without a college degree I would probably be going nowhere in my life. So, I decided to go to college. There were many reasons backing my decision to go to college: I wanted to make a better life for myself. I waneted to find a job where I would not be living paycheck to paycheck, like my parents have had to. I wanted to encounter things that I never realized could even exist, and to take classes taught by passionate instructors. But most of all, I wanted to prove that I could be successful. I did not do the whole "high school experience" thing at all. During my four years in high school, I was antisocial, and spent most of my time at home. But now that I am in college, I can experience so many things that I skipped out in in high school. It was a huge dream of mine to have friends, to be social,......

...January 28, 2012 A New Life As I wobbled in the cold and lonely bright room, I could spell the aroma of cleanliness hanging from the ceilings. I sat in a cold hard bottom chair patiently waiting on 0500 hours to come. As the time was winding down I had butterflies flying in the inside of my stomach. My palms were dripping with sweat and my eyes were telling the story of a weary one. All of a sudden I heard a loud buzz the doors came swinging open. I looked at the old time machine and seen that the moment I’ve been waiting for has finally arrived. Approaching me was a tall and skinny figure with a long white coat and black shoes that glided across the floor like skates. Those big blue eyes that I seen through those specs was to die for. Coming out of my fantasy with this Doctor I now knew that it was time for the big birth. He spoke fluently in his barrow town voice, “ Ms.Luckett are you ready” my reply was a smile so wide you could see the breakfast I had two hours before. He escorted me through the halls that seem as if they were never going to end. I was greeted by so many different smiles and body languages. Finally I had made it to my destination! The room was very dark and cold. In the room it was two chairs with floral printing on them that rocked back and forth. A television that looked like it was there since the WWII, and a bed that looked like it was hard enough to drive a car upon. The doctor gave me the ropes of the procedure and stated that I......

In the times that this nation is in right now the decision to start a new career is not the most logically decision. The decision is not only made upon the person wanting to start a new career, whom ever that may be needs to make sure not only they can afford to take a break in job stability and their family supports the decision as well. The decision to start a new career not only is cost effective as well as the amount of time that it will take to be trained in a new environment can be costly to the person, company, and family. When looking to start a new career it takes time, patience, and dedication to be able to all a sudden change the career path.

Everyone has experienced both expected and unforeseen events that have made profound impacts on them. On April 19, 2013, I underwent the most profound imprint of my life, giving birth to my daughter, Sydney Lillian Diggs. I remember the day I found out I was pregnant. It was one of the happiest and scariest days of my life due to a previous miscarriage just a few months before. I took two home pregnancy tests, then another at my doctor’s office to make sure I was not dreaming. The doctor confirmed I was pregnant! My fiancé and I listened to the baby's heart beating. It was the most absolutely amazing experience. My emotions went from laughter to crying tears of joy. A few weeks later we went for the ultrasound. We were on our wonderful journey to become parents. I had my delivery plan all mapped out. Since my fiancé works two hours away, I had contingency hospital plan. My sister who lives a mile from me, was my back up plan. In addition, I have a close friend Akilah that lives two blocks away has a flexible schedule during the day. All of Sydney's clothes and bedding were washed and organized. My bags were packed.

Molecules of Life

...MOLECULES OF LIFE 90% of the human body is composed of just four elements. They are carbon, hydrogen, oxygen, and nitrogen. These elements combine to larger units called molecules. There are two types of molecules in our bodies; organic and inorganic. INORGANIC MOLECULES are not made of carbon atoms. 1. SALTS are found in body fluids. They are needed for muscle contraction and nerve conduction. 2. WATER The body is about 70% water. All of our body’s chemical reactions require it. It keeps the body from overheating It also prevents drastic changes in temperature. Last spring, a baby finch collapsed with exhaustion on my patio. Since it was exhausted, it probably wasn’t good at finding food and water yet. That means it was dehydrated and hungry. I knew to get an eyedropper and give it water with sugar in it because those are the two main things it needs right away. We discussed water, now lets get to sugars. ORGANIC MOLECULES are made of carbon, which is what our body is mostly made of. The three main types of organic molecules in our body are carbohydrates, lipids, and proteins. 1. CARBOHYDRATES are molecules that store energy a short time. a) SIMPLE CARBOHYDRATES known as sugars, such as those found in candy. They are used for a quick source of energy, and they are burned off fast. The main sugar form is glucose. b) STARCH is a storage form of glucose in plants, especially flour and potatoes. When we eat breads, potatoes, and cakes, we convert it to glucose. These......

New Gate of Life

...been a catastrophe so far. At lease once a day, I thought about where my parents were. My grandmother showed love for me in place of them. Although there were many people in my life who loved me, the thought of my parents still nagged at the back of my mind. “What could I have done wrong to be left by the people who brought me into this world? Was it my looks or my personality?” These thoughts were always sitting in the back of my conscience. Sometimes, I would lie in bed at night, unable to sleep, and I would feel this overwhelming sense of rejection. On most days, I felt as if the gates of my life were closing rapidly in my face. Growing up, my grandmother was always my role model, but I never imagined I would be living with her. My parents decided to live in sin rather than work towards the gates of Heaven. They were driven by rebellion and deceit every day, and the responsibility of taking care of their only child just wasn’t a priority to either one of them. As I tossed and turned in bed, I wondered what the talk of the lunch table would be the next day. I always seemed to be the center of attention in a negative way. I was often referred to as the “new girl” or the “loner with the blonde hair.” Being the new girl was something I often pondered anxiously when I lived in Texas. The workload at my new school was so much more than I had anticipated. In addition, jealousy was an issue I fought every day. Most of the girls at school were the stereotypical cheerleaders who......

...English 1010 6 June 2015 A New Life Humans are like tea bags. You do not know your own strength until you get into hot water. Growing up I always had it made. I had the security and support of my family plus financial support. I did not understand the true meaning of responsibility until maybe late last year when I found out I was pregnant. That day changed my life. I sat inside Starbucks and reflected on my life up to that point. I knew from that day on; that if I plan on keeping the baby I had to prepare myself mentally, physically, and financially. Late last summer I was feeling a bit discourage about life and where I was headed. I had no plans or goals set for myself. I was also feeling a bit depressed that I did not know what I wanted to do with my life. I knew I wanted to get back into school as a start to get me out of my dark clouds, but my living situation at the time did not permit me to do so. I knew God had a plan for me though because I felt his presence the most around that time in my life. He spoke to me through the people I was around and books I read at the time. I believe he was mentally preparing me for what was coming. My boyfriend and I also became closer around that time as well and talking to him helped me tremendously with my future plans on what I wanted to do. I was feeling a little better about myself now that I had written down some goals. Soon after, I find out that I am pregnant. Emotionally, I feel numb. By this time, I am still not in......

...The Oil Connect Schanaque Watson Strayer University PAD 540 May 19, 2015 [Instructor Name] The Oil Connect Introduction Oil has been a problem in the United States for years. We have been fighting with countries like Iran, Russia and so many more. According to history.com, The 19th century was a period of great change and industrialization. The iron and steel industry had new construction materials, the railroads connected the country and the discovery of oil provided a new source of fuel. In 1901, Spindletop geyser drove huge growth in the oil industry. More than 1,500 oil companies had been chartered, and oil became the dominant fuel of the 20th century and an integral part of the American economy. World War II, 1945, made the oil industry a key American resource. Oil company research and executive leadership played major roles in the conflict. Because of World War II, research increased the number of products made from petroleum and natural gas, including the explosive and artificial rubber. The Jersey-Dupont jointly owned product, tetraethyl lead, upgraded gasoline to improve airplane speed. Oil tankers supplied gasoline for the Allies at great risk from submarine attacks. The government rationed gasoline and controlled prices during the war. In the last analysis the war ended the delusion that American supplies of crude were unlimited, so that the industry and the securing of oil became a top priority for both foreign and domestic policy.(Giddens) ...

Molecules of Life

...Reading guide notes: the Molecules of Life Part 2 1. Seven different functions of proteins in the body are structural proteins, storage proteins, contractile proteins, transport proteins, defensive proteins, signal proteins, and Enzymes. Structural proteins provide support for hair, horns, feathers, spider webs, and connective tissues. Storage proteins provide a source of amino acids for plants and animals that are developing such as seeds and eggs. Contractile proteins are primarily in muscles. Transport proteins transports oxygen from an animals lungs to other parts of the body. Defensive proteins protect the body as antibodies. Signal proteins conveys messages between cells. Enzymes change the rate of a chemical reaction without being changed. 2. There are 20 different kinds of amino acids in a protein. Amino acids consists of a central carbon atom bonded to four covalent partners. Three of the attachments are consistent within each amino acid, a carboxyl group, an amino group, and a hydrogen atom. What makes each amino acid different from another is that the fourth bond of the central carbon has a different radical group. 3. A protein polymer is called a polypeptide. A polypeptide is made of 100 or more amino acids bonded by dehydration reactions. The bonded amino acids are called peptide bonds. 4. The difference between a polypeptide chain and a protein is that a protein needs more than one polypeptide to be functional. Polypeptide is only one part of the...

...school at Gloucester. Thomas Edward Brown profoundly influenced on the young Henley, he encourages him to read books and to study literature. After few months, Henley passed the local Oxford examination with an excellent result, but due to financial and ill- health made it impossible to begin his study. William Ernest Henley, throughout the poem he uses certain words and phrases which bring out the image of the format while at the same time keeping the idea of self- respect and most important, pride. Henley never subscribed to any organized religious belief at any point in his life, however. At the very least he sensed a power that controlled and manipulated the universe. While in the hospital he realized that it was only through his own inner power that he was able to overcome his overwhelmingly despairing circumstances. Henley developed a philosophy that the individual must lead an active life and never regret dreams that may have been turned into reality. The closest that Henley ever came to admitting to a greater power was in "Invictus" "I thank whatever gods there be." Though it mentions the possibility of gods, the poem lacks any hint of faith. The speaker is agnostic and very well may be an atheist. And so, Invictus serves as a testament to Henley's own personal philosophy, as it demonstrates the individual's own inner strength and indomitable free will as being his/her the only resource for survival. Ever since Henley was diagnosed with tuberculosis, his live......

...LAP’recyous Bradley MS. Hester English ll 01-02-2016 Racism Racism has been a major problem in society from the 1950’s until this day. Racism is discrimination directed against someone of a different race based on the beliefs that one’s own race is superior. Racism is a major issue that affected millions of people, and still effects many people. These beliefs are a main cause in riots, boycotts, and other outrages. Many different groups existed during the Reconstruction era, but the groups disagreed on what was needed to move America forward. Southern white conservatives did not want blacks to own property, have political power, or even have the opportunity to vote in elections. The white Southerners so strongly believed that whites were superior that they worked hard to make sure legal restrictions were in place to prevent the blacks from gaining any type of equality or power. The freed slaves merely wanted the opportunity to continue the “family-based communal work methods” as opposed to having to accept the individual piecework structure. In addition, the former slaves wanted to be able to continue to live on the land their ancestors had farmed. The contract labor system was implemented in 1866 under the supervision of the Freedmen’s Bureau and provided fixed wages for workers for one year, with part of the pay held back until the crops were harvested. In Carl Schurz’s Report on Conditions in the South (1865), it stated that the freedmen......
