Jean Watson Influence On The Structure Of Dna

Understanding DNA can take a lot of studying and confusion to even get the general idea of the concept. The structure of DNA is very complicated and complex to understand, but researchers James Watson, Francis Crick, Maurice Wilkins, and Rosalind Franklin all developed the idea of the DNA structure in 1953. Deoxyribonucleic Acid is found in the nucleus of the cell. It is a double stranded molecule that contains the genetic code and is the main component of chromosomes. DNA is the blueprint of organisms. Nucleotides are the basic unit of DNA and they are made up of sugar, phosphate, and one of the four basis including adenine,

The pictures were shown to James Watson and Francis Crick by Maurice Wilkins. They were then able to confirm their theory about the 3D structure of DNA. In 1962, they were awarded the Nobel Prize in Physiology or Medicine for solving the structure of DNA. The Nobel committee could not award it to Franklin because the Nobel prize could only be shared by three people and also because she was already dead (DNA from the Beginning, 2011)

In the early 1950s, the race to find the structure of DNA was in full swing. The search was being conducted at three different colleges. At the California Institute of Technology, Linus Pauling,

Over the course of the modern age, the human body was still a mystery waiting to be solved. The body contains secrets one can only hope to discover. Over the twentieth century, scientists tried to understand one of the most complex concepts in the biological field. DNA (Deoxyribonucleic acid) was at the forefront of research. Several theories claimed to have solved the structural concept of DNA. However, it was not until Francis Crick and James D. Watson discovered the true structure, the double helix. However, many potential models of DNA had passed through the biology field until eventual lose of credibility. The past models would contain a fixed detail that would make the entire concept invalid. In James D. Watson book, The Double Helix, he illustrates his path amid incorrect theories until he reaches the model that is taught around the world today.

When Pauling and Cory attempted to come up with the structure of DNA, they thought that the DNA helix was a triple helix. This was because they misinterpreted DNA A structure and concluded that the phosphate and sugars were on the inside and the nucleotide bases were on the outside. Watson and Crick said this was not possible because phosphates can’t fit together inside the helix without breaking their molecular bonds. The studies Watson and Crick made were based off of DNA B molecule from the X-ray of DNA B taken by Rosalind Franklin that had low concentration, rather than A DNA which was high in salt concentration that gave Pauling an improper representation of the DNA helix. Pauling and Cory stated that the helix was made of three helices, Watson and Crick disapproved of this concept because phosphate backbones are negatively charged, it was impossible to put three negatively charged strands with each

2. What role did James Watson & Francis Crick play in our understanding of DNA’s structure? They discovered the 3D structure.

Watson of opinion that anything that Crick would touch would eventually be regarded as the Gospel of that field due to his brilliant insights into someone’s work. (Page 4) This the very first impression of Watson that Crick who was merely meagre in his own experimental work for his Ph.D as represented by him flooding the hall way with water because he had neglected to prepare his experimental equipment properly. Whereas he was extremely quick in intervening on other’s lab work and providing insights on as to how should the experiments proceed going further. This is my opinion is the start of this coalition between sketchy Watson and intrusive Crick alliance that obtained and used works of many prominent scientists such as Chargaff, Donohue, Wilkins, Franklin yet failed to give proper credit due to each one of them with a marginal exception of Wilkins.

Also he helped with mapping cancer to help people or warn others, so they will be able to find if they have it. James helped out everyone on this planet and those who are sick or are sick but don’t know it. To be recognized in the scientific community you have to do something amazing. Crick and James Watson's first look toward taking in the structure of DNA missed the goal, but their second look took place in the spring 1953 and brought about the match of the ladder helical look. Which takes after a stepping stool. Their model added how the DNA particle could copy itself. Watson and Crick had looked the work of English scientist Rosalind Franklin, a partner of Maurice Wilkins' at King's College London, to land at their noteworthy disclosure, notwithstanding, her commitment to their discoveries would go generally unrecognized until after her she died. Franklin had made a few unpublished working papers talking about the basic characteristics of DNA, and with her understudy Raymond Gosling had taken a X-ray diffraction picture of DNA, known as Photo 51, which would get to be urgent proof in recognizing the structure of

Many people throughout our nation do not know that it was more than Crick and Watson that led to this remarkable discovery through our history. Another aspect that is astonishing is that fact Crick and Watson were so close to giving up on the research of DNA and it's double helix structure. They believed it would impede science and it's research. It held

What could have been a successful collaboration becomes a large setback for Watson since he and Crick now had to basically start from the beginning. As the search continues, each scientist in this rivalry is finding a possible solution but then being disproved by another since they suspend crucial pieces of the puzzle from each other. Although Franklin places them in a state of near defeat, Watson and Crick find the information they need in a questionable manner.

In “The Race for the Double Helix” there were five major characters that helped make the discovery of how DNA looks. The first, James Watson, was one of the more major and important characters. He and his partner, Francis Crick, made the final model for DNA. Watson however was always trying to find pieces to the puzzle by scavenging from over scientists discoveries. He would travel the world just to meet up and talk to different scientists.

When James Watson and Francis Crick explained their DNA molecule to Wilkins and Franklin, they both knew something was wrong. Watson had tried to remember what Franklin had said in one of her lectures on the DNA molecule, but he was going off just his memory so most of it was wrong. Linus Pauling was on his own race against time to try and beat Franklin and Wilkins, they had been waiting to see what Pauling had come up with, but as they read his report they knew it was wrong. Franklin was a very “careful scientist,” she wanted to look at more photos before she shared what she had found. What Franklin didn’t know was in the spring of 1953, Wilkins had shown Watson one of her best x-ray photos. Watson had asked if they could start to work on

It is constantly recurring throughout his autobiographical statements as he recounts how each small discovery by the scientists he encounters help find a simple explanation, model for the structure of DNA from the complex ideas and evidence they began with. It is seen that each scientist had something to contribute whether it was a discovery or knowledge in their area of expertise that was beneficial in the discovery of the DNA structure. For example, when Crick saw Crystallographer V.Vand’s discovery of “a theory for the diffraction of x-rays by helical molecules” though he thought the theory was invalid it peaked his curiosity in finding an accurate theory. Furthermore, in Watson’s interview it is seen that when it comes to science he thinks that if there is scientific knowledge that will affect human beings’, scientists, the scientific community should work to ensure that they understand the knowledge and

In 1953 four scientists: James Watson, Francis Crick, Maurice Wilkins and Rosalind Franklin completed a DNA model which they created using observed X-ray diffraction patterns. This model showed how the structure of DNA was able to transmit genetic information from parents to their offspring.

Rosalind Franklin’s work on DNA was crucial in discovering the composition of the human body as a whole. Her x-ray photo revealed a double helix structure and she also discovered the A and B form of DNA. She worked through the adversity of being a female in a predominately male dominated realm and made remarkable findings that were eventually stolen. She adapted to a new lab with antiquated technology. Before this discovery, the structure of DNA was thought to be simple. Scientist, Watson and Crick, started with the wrong structure of DNA from a misinterpretation of notes from one of Franklin’s presentations. Unlike Watson and Crick, Rosalind Franklin could explain DNA and how it worked.
