The essential component of life can be acknowledged and is made up of a nucleic acid known as DNA. DNA is the abbreviated form for the word deoxyribonucleic acid and it is the “carrier of genetic information” (McMurry, Ballantine, Hoeger, & Peterson, 1992, pg. 775). DNA contains the genetic instructions that are needed for an organism to develop, survive, and replicate, as it plays a crucial role in living systems that makes each species unique and distinctive. The multifaceted material is stored in every cell of every living organisms and it contains information about our nature, appearance, performance, etc. With the instructions that it contains, DNA is passed from the adult organism to their offspring during reproduction. (McMurry, Ballantine, Hoeger, & Peterson, 1992, pg.777).
LOCATION OF DNA
DNA is located inside the cell called the nucleus. Due to the cells being extremely small and each organism having many DNA molecules per cell, each of the DNA molecules must be firmly packaged and this is called chromosome. A chromosome is a lone piece of DNA
DISCOVERY OF DNA
The discovery of DNA is quite mind-blowing. Rumor has it that James Watson and Francis Crick discovered DNA, but they actually did not. It all started in 1869, with a well-known German biochemist named Friedrich Miescher who isolated, analyzed, and recognized a distinctive macromolecule known as DNA. Years later, on the morning of February 28, 1953, Watson and Crick came into the picture, as they announced that they “had discovered the secret of life” (Markel 2013). Their discovery of the double helix made them publish a paper in the 1953 issue of Nature, describing the structure of DNA, which resulted them to receive the Nobel Prize in 1962.

...her child’s whereabouts. Ironically, the jury undisputedly found her “not guilty of murder, manslaughter, and child abuse” and Casey Anthony was not charged with first-degree murder, as there was no equitable doubt.
These two cases shares many similarities, yet differs in a few ways. Both cases at one point were overturned, but remained slightly unresolved. Between these two cases, the murder of Caylee Anthony had America outrage with anger when Casey Anthony was found “not guilty”.
DNA is continuously evolving as it has developed various aspects of illicit cases, as well as playing vital roles in all cellular systems. The discovery of DNA has impacted and will trigger the fuel of new findings later in the future. DNA does not only significantly affect a cell’s function, but it aids the species to develop and reproduce, despite the altering conditions.

- The Dna is made out of two long twisted strands called the double helix. Dna is short for deoxyribonucleic acid, which is a molecule that carries information into humans and all living organisms. The gene is a segment of Dna that is passed down from a parent to its children and confers a trait to the offspring. They determine weather you look like your mom, dad, or both of your parents. You either inherit their good genes or there not so good genes. (www.//geneed.nim.nih.gov/) The Dna was first observed by Swiss Biochemist Fedric Miescher in the late 1800’s....

- This book is about the process that the author, James D. Watson, and his colleague, Francis Crick went through in order to discover that the structure of DNA is a double helix. To begin the story Watson recounts how he met Crick, who was a rather energetic character that actively engaged himself in in work. Watson then goes more in depth about the relationships that he had with other scientist such as Maurice Wilkins and Rosalind Franklin, or “Rosy” as she was referred to by Watson in the novel....

- 1. Franklin and Wilkins believed that x-ray diffraction was the correct tool and there is no helix; he (Wilkins) did this with the help of Franklin expertise in crystallography. “It was downright obvious to her that the only way to establish the DNA structure was by pure crystallographic approaches. As model building did not appeal to her, at no time did she mention Pauling 's triumph over the α-helix”(26). Although Watson and Crick both were also influenced by Wilkins and Franklins idea,they went on with looking at DNA with models and with two “chains” (the sugar phosphate) that wrapped around each other also know and the two helix....

- James Watson's The Double Helix James Watson's account of the events that led to the discovery of the structure of deoxyribose nucleic acid (DNA) is a very witty narrative, and shines light on the nature of scientists. Watson describes the many key events that led to the eventual discovery of the structure of DNA in a scientific manner, while including many experiences in his life that happened at the same time which really have no great significant impact on the discovery of the DNA structure....

- The Double Helix "The discovery of the structure by Crick and Watson, with all its biological implications, has been one of the major scientific events of this century." (Bragg, The Double Helix, p1) In the story of The Double Helix, James Watson tells of the road that led to the discovery of life's basic building block-DNA. This autobiography gives insight into science and the workings within a professional research laboratory that few members of society will ever be able to experience.... [tags: Double Helix Essays]

- This paper explains the history of DNA, deoxyribonucleic acid, and its twisted or weird history. DNA is a genetic material in our cells that gives us our different traits. It is made of three essential things, which are phosphates, sugars, and nitrogenous bases.There are four types of bases cytosine, guanine, thymine, and adenine. Adenine and guanine are purines meaning that they have two rings. Cytosine and thymine are pyrimidines meaning that they have one ring. Adenine pairing with thymine and guanine pairing with cytosine.... [tags: DNA, Francis Crick, Nucleic acid, RNA, Gene]

- The Discovery of the Double Helix Today, the 1953 discovery of the double helix, “the twisted-ladder structure” of DNA, by James Watson and Francis Crick, constitutes one of the greatest breakthroughs in the history of science. The discovery has given rise to the molecular biology of today and generated new insights into genetic coding upon which today’s multi-billion dollar biotechnology industry is founded. It laid the groundwork for other scientific achievements, including modern forensics and the mapping of the human genome.... [tags: DNA, Francis Crick, Gene, Genetics]

- Molecular Biology and The Double Helix Molecular biology became a new field scientific field in the 1950s that built upon 19th and 20th century cellular and genetic investigations. Molecular studies pushed physical scientists and their instruments to study the life sciences that yielded plenty of discoveries. These investigations allowed for the discovery of proteins, nucleic acids (RNA/DNA), and the structure of the double helix. Justus Von Liebig (1803-73) continued protein molecule analysis after the work of Gerardus Mulder in the 1830s.... [tags: DNA, Francis Crick, James D. Watson, Light]

- In The Double Helix, Watson does not hide how competition influenced his work on DNA structure. Throughout his book, Watson references his main competitor, Linus Pauling, a chemist from The California Institute of Technology: In Chapter 20, Watson was glad that Pauling did not pose “an immediate threat on the DNA front” (151) since he had directed his attention to α-helices. In Chapter 22, Watson and Crick celebrate Pauling’s published error on hydrogen bonds, stating, “Though the odds still appeared against us, Linus had not yet won his Nobel” (175-6)....

- A Helix-Shaped Maze Genetic engineering is a concept that induces terrifying reactions in many people. Visions of disgusting and inhuman mutations tend to flash across the minds of those adamantly against any form of bioengineering. Genetic engineering is a science that is used to manually add DNA into an organism. The world has practiced forms of genetic modification for centuries from the simple to the extreme. Humans turned wolves into common household pets with a technique called selective breeding.... [tags: DNA, Gene, Genetics, Mutation]
