Assignment 3.05 DNA DNA, deoxyribonucleic acid, is the stuff in humans and almost all other organisms. About every cell in you and everyone else's body has the same DNA. DNA is usually located in the cell nucleus (nuclear DNA),however small amounts of DNA can be found in the mitochondria (mitochondrial DNA or mtDNA). The DNA has information stored as a code created by four chemical bases: adenine (A), cytosine (C), guanine (G), and thymine (T). Each base is connected to a sugar molecule and phosphate molecule.…
Several Advancements in technology produced a fast DNA sequencer in the 70’s, and in 1983, Karv Mullis created what is called Polymerase Chain Reaction (PCR). PCR is a very simple and inexpensive technology that is used to amplify and produce large amounts of copies of a segment of DNA. Now this has become one of the most significant scientific advances in molecular biology, PCR amplification is used every day to diagnose diseases, its also used to identify bacteria and viruses, and to match criminals to crime scenes. PCR has revolutionized the study of DNA to such an extent that Dr. Mullis was awarded the Nobel Prize in Chemistry in 1993.…
a) Francis crick- Discovered the structure of that DNA that it's shaped like a twisted ladder and understood the way it replicates. b) Rosalind Franklin- She discovered the dimension of DNA strand and that the phosphate group was on the outside of the helical structure. c) James Watson- Together with Francis they discovered the structure of DNA and that he also discovered that hydrogen bonds were the correct length and were straight.…
1. DNA Structure and Function DNA is the type of organic compound that stores the genetic information in a living organism. DNA is made up of two strands of nucleotides, which include a phosphate group, five carbon sugar, and a nitrogenous base. Each individual strand in held together by strong covalent bonds (a bond formed as a result of the distribution of electrons between atoms). The two strands are then joined to each other by hydrogen bonds between complementary bases.…
As a nurse, this was very interesting. To have to ability to know and understand how some differences make some people susceptible to certain diseases, such as diabetes, heart disease, stroke and autism, these findings could impact our society and the healthcare industry in a major way. As well as trying to understand what it is about genetics…
1. In the article entitled, “The DNA Mystique: The Gene as a Cultural Icon,” authors Dorothy Nelkin and Susan Lindee argue that the gene has influence as a social symbol outside of its biological domain, becoming something like a “magical force”. Nelkin and Lindee describe the gene as, “powerful, deterministic, and central to an understanding of both everyday behavior and the “secret of life””. The popular media has helped to shape the general public’s view of the gene as an all powerful device with the capacity to determine one’s entire behavior.…
He went on to say he hoped that everyone was equal, but he countered that “people who have to deal with black employees find this is not true.” Watson is no stranger to irrational annotations and controversies. He and Francis Crick relied in part on Rosalind Franklin’s X-ray diffraction data to determine the structure of DNA. They could not have proposed the correct structure as early in 1953 as they did without access to Franklin’s data. When they were awarded the…
McGrinn 1 Elizabeth McGrinn 1 Feb. 2017 Mr. Sanders 6th Period There have been many different scientific discoveries throughout history. Scientists have found different galaxies, medicines that cure the sick, or someone like Gregor Mendel, who discovered chromosome genes.…
James Watson along with Francis Crick helped discover what we know about DNA today. They helped shape what we know about DNA and changed the world with scientific contributions. James Watson along with his colleagues helped shape the modern science of today with his many studies of DNA, cancer, and genomes. James Watson was born in Chicago, Illinois on April 6th, 1928. When he was young he attended Horace Mann Grammar School for 8 years and then attended South Shore High School for two years.…
Although there isn't always a definite answer on who did the crime, DNA technology has evolved and is a great tool to provide evidence for a case. With that said, DNA alone is not enough to find a suspect guilty or not guilty. DNA is evidence used to determine who committed the crime, how they committed the crime, or if they are innocent. In 1999, in Australia, a girl was raped, and named Frank Button as the criminal who committed the crime. The sheets and pillowcases from where the assault took place were sent to the laboratory, but not tested.…
Having a difficult time understanding the text leaves me feeling a bit at a loss for writing this essay. I am hoping that in my attempt to put something together on paper it will somehow make sense and hold some relation to the task that has been appointed. As I understand the difference between an argument of definition or causality I am left confused after reading the Zizek chapter three times. It seems that the text and his ideas although are supposed to be about ecology tend to take paths into other ideas, that I cannot seem to keep up with. When first reading the chapters I was feeling that his argument was more of an argument of causality; the idea that there is a cause and effect happening in with the word ecology and what it supposed to mean and what it actually means.…

DNA is the part in all human’s bodies that make people who they are. Every one in the world has their own DNA unless that person has an identical twin. DNA is working in every persons' body each day. This research paper will explore how DNA affects everyone’s life. What DNA is, the structure of each DNA molecule, some interesting facts about DNA, and what a gene is will be addressed in this document.…
DNA sequencing and information is useful in many fields of science and technology. DNA ideally can be used to identify specific organisms because most organisms don’t possess the same DNA.The use of DNA to try to identify specific organisms is called DNA fingerprinting. DNA fingerprinting involves creating a DNA fingerprint using gel electrophoresis, which is the process by which DNA is broken down into fragments and then sorted by positive electrodes (after negative electrodes repel them from the other side. And as this happens the DNA strands for lines of different lengths resulting in an identifiable pattern. There are wide array of uses for DNA fingerprinting.…
The Future for Human Genetics People have been around long enough to know that everything changes (for the better or worse). Within the past few years, there has been a lot of debate over the scientific breakthrough of being able to modify the human genome. Many doctors and scientists have welcomed the idea with open minds while others are hesitant to become involved. Some see the dangers involved with the process while others see the endless possibilities coming out of this revolutionary discovery.…
