“Gene-ius” Scientists Discover DNA
By DiNA Madan

James D Watson
Watson was born on the 6th of April 1928 in Chicago and studied at the Universities of Chicago, Indiana, Copenhagen and Cambridge University where he joined Francis Crick in the attempt to find the chemical structure of living matter. http://t1.gstatic.com/images?q=tbn:ANd9GcQUceZSNxrQ7_IAvEm3D1SuT4wWb-g7jm-xI4fOMKI2mJvSMixaUg The Double Helix
In 1953 Watson and Crick presented the three dimensional double-helical model as the first DNA structure. Scientists today have only made some changes to Watsons and Cricks original model but have kept major features of their structure, like the genetic code, A pairs with T and G pairs with C.

The original DNA model made by Watson and Crick in 1953

Francis Crick http://t1.gstatic.com/images?q=tbn:ANd9GcR3541FNUnCyNmwIJ8L1ZaZJ5SeFS8Ey06pX0U8XIZcZOxhf9v6SQCrick was born on the 8th of June 1916 near Northampton and studied Physics at a University in London. In 1947 he changed from Physics to Biology and started to work at Cambridge University at the Medical Research Unit, and by 1951 Crick and Watson began working together.

A modern DNA model made by scientists in the last year

Maurice Wilkins http://t3.gstatic.com/images?q=tbn:ANd9GcR-P_NxDsRFjAUofIIj_pM_eepdT1QYOsNYM14hI8_Ag3gy3jgDNwWilkins was born on the 15th of December 1916 in New Zealand and attended the University of California, Cambridge and Kings College in London. Wilkins with the help of colleague Rosalind Franklin made crucial discoveries helping Watson and Crick obtain the DNA molecule.

Awards won by the scientists:
Watson, Crick and Wilkins all won the Nobel Prize in Physiology or Medicine
Watson and Crick won the John Collins Warren Prize of the Massachusetts General Hospital
Watson, Crick and Wilkins won the Lasker Award
Watson and Crick won the Research Corporation

    Rosalind Franklin was a chemist who made the first DNA structure in 1953. A DNA model is a model of someone's DNA. DNA stands for Deoxyribonucleic Acid.A DNA strand is used to figure out a person’s physical and mental information. There are two forms of DNA an “A” form and a “B” form. (Franklin 2015) Franklin found this out by putting a DNA fiber under a x-ray machine Franklin refined herself. Franklin and Maurice Wilkins used Franklin’s x-ray photo called photograph 51 and Wilkins published first and so he got a nobel peace prize in 1962. (Franklin 2015) Franklin was then given some of the credit and was written about in the article of the newspaper.…

    DNA is composed of two polynucleotide strands wound together into a structure known as a double helix. Each nucleotide consists of a sugar base .Nucleotides form together creating a sugar phosphate backbone to each strand. There are three forms of DNA that differ significantly. The most common, B form, is the structure most people have heard of. It consists of the right handed double helix, with a large major groove and a smaller but accessible minor groove. These grooves are spaces between the backbones which allow access to the bases for interactions with proteins. A form DNA is also a right handed helix, but as yet has not been found in organisms, and only exists in synthetic environments. It has a wider, flatter structure. Z form DNA is found in living organisms, but is a left handed helix, meaning it twists in the opposite direction.…

    * There has been a major effort in the history of science to figure out the structure of DNA. Having a double standard helix DNA has a uniform a diameter in its entire length. The helixes fit within a defined three dimensional space because they are both right handed. Polynucleotide chains are held together by the bases in the (center) hydrogen bonding with the bases on the opposite polynucleotide. Two polynucleotides are form around the outside of the helix with the bases extending into the center. Known as complementary base pairing; hydrogen bonding is a very specific process. Scientist had identified all the atoms and knew how they were bound together. What was not understood was the capacity to store genetic information, copy it and pass it from generation to generation, and the specific three dimensional arrangements of atoms that gave DNA its unique proprieties.…

    J.Ernest Wilkins Jr. was born November 27, 1923, in Chicago, IL to the late J. Ernest Wilkins Sr. His father was a lawyer who went on to become President of the Cook County Bar Association in the early 1940s (Cook County is in northeastern Illinois and Chicago is in that County), and Assistant Secretary of Labor in the Eisenhower administration of the 1950s. His mother Lucile Robinson had been educated to the level of a Master's Degree and was trained as a schoolteacher. He entered the University of Chicago at the age of only 13 there becoming the youngest student ever to enter that college to study mathematics. He received great publicity when he graduated with his A.B in Mathematics from UCHI in 1940 at only 17.…

    Because Watson and Crick were the ones who lead the research to answer the DNA problem, they were awarded credit for the discovery even though there were many other scientists who contributed their skills and findings to the discovery. After Maurice and Rosalind Franklin, another scientist at Maurice's lab, read the paper that was to be sent to Nature, they objected that a scientist in their lab, referred to as Fraser, needed to be referenced because he "had considered hydrogen-bonded bases prior to [their] work." (128) Even if a scientist did not get equal credit for a discovery, they were given credit as far as the information that they contributed goes. A big exception in the case of giving out due recognition in the history of The Double Helix is that Rosalind's contribution to the discovery was not acknowledged nearly as much as it should have been, most likely because of the fact that she was a woman and science was a boy's club at the…

    Joseph Priestley was a famous scientist during the 18th century best known for is discovery of oxygen. He was born in Birstall, England on March 24, 1733. When Joseph was a boy he attended many different schools. He was sick very often when he was little this caused him to miss a lot of school. He began to learn to teach himself at home. This skill became very useful to him, as he got older. He then could very easily teach himself new concepts without a teacher. Then in 1752 Joseph began to attend Daventry Academy, he thrived in this environment. This Academy allowed him to get an excellent education in philosophy, science, and literature. Joseph then graduated in 1755, after receiving his education most of the jobs he received had to do with…

    Galileo Galilei was born on the 15th of February in 1564 in Pisa, Italy. He would become a household name in modern history due to his many achievements to science and mathematics. Galileo studied under Jacopo Borghini for two years. Galileo was then educated at the Camaldolese Monastery at Vallombrosa for most of his younger years. He would eventually enroll in the University of Pisa for a degree in medicine. Then, after accidently attending a geometry lecture, Galileo switched to the study of mathematics.…
