Watson wanted to explore the structure of DNA, and his interests did not coincide with Kalckar's. After obtaining some results from his phage and other experimental research [32] conducted at Indiana University, Statens Serum Institut Denmark , CSHL, and the California Institute of Technology , Watson now had the desire to learn to perform X-ray diffraction experiments so he could work to determine the structure of DNA. That summer, Luria met John Kendrew , [33] and he arranged for a new postdoctoral research project for Watson in England.

The double helix : a personal account of the discovery of the structure of DNA

Nearer Secret of Life. Oughton were some of the first people in April to see the model of the structure of DNA , constructed by Crick and Watson; at the time, they were working at Oxford University 's Chemistry Department.

According to the late Beryl Oughton, later Rimmer, they all travelled together in two cars once Dorothy Hodgkin announced to them that they were off to Cambridge to see the model of the structure of DNA. Watson subsequently presented a paper on the double-helical structure of DNA at the 18th Cold Spring Harbor Symposium on Viruses in early June , six weeks after the publication of the Watson and Crick paper in Nature. Many at the meeting had not yet heard of the discovery.

Watson, Crick, and Wilkins were awarded the Nobel Prize in Physiology or Medicine in for their research on the structure of nucleic acids.

They used some of her unpublished data—without her consent—in their construction of the double helix model of DNA. Franklin told Crick and Watson that the backbones had to be on the outside; before then, Linus Pauling and Watson and Crick had erroneous models with the chains inside and the bases pointing outwards. The X-ray diffraction images collected by Gosling and Franklin provided the best evidence for the helical nature of DNA.

Watson and Crick had three sources for Franklin's unpublished data: Her seminar, attended by Watson, [43] Discussions with Wilkins, [44] who worked in the same laboratory with Franklin, A research progress report that was intended to promote coordination of Medical Research Council -supported laboratories.

According to one critic, Watson's portrayal of Franklin in The Double Helix was negative and gave the appearance that she was Wilkins' assistant and was unable to interpret her own DNA data.

Franklin consulted with Watson on her tobacco mosaic virus RNA research. Franklin's letters begin on friendly terms with "Dear Jim", and conclude with equally benevolent and respectful sentiments such as "Best Wishes, Yours, Rosalind". Each of the scientists published their own unique contributions to the discovery of the structure of DNA in separate articles, and all of the contributors published their findings in the same volume of Nature.

However, a Nobel Prize can only be awarded to a maximum of three people. Who would have lost out? Would perhaps the medical prize have been awarded to Watson and Crick and the chemistry prize to Franklin and Wilkins? Sadly we will never know.

Rosalind Franklin died from ovarian cancer before the awarding of the Nobel Prize in Physiology or Medicine which was jointly awarded to Francis Harry Compton Crick, James Dewey Watson and Maurice Hugh Frederick Wilkins "for their discoveries concerning the molecular structure of nucleic acids and its significance for information transfer in living material". Do we vilify James Watson and triumph Franklin as some sort of wronged feminist icon?

I know what I believe. Probably because it was one of the first you learned in your biology class.

The Double Helix

And Why? You should read it because you want to be a smarter fellow; after all, the discovery of DNA changed so many things about the world. Read it for the gossips and the unabashedly honest behind-the-scenes depictions of celebrated scientists — if you want juicy details from a world you taught had none.

And read it for pleasure — if you are tired of novels and other types of fiction. Because — sometimes — real life is just incalculably more interesting. About James D. Watson James D. Watson is an American geneticist, molecular biologist, and zoologist, a co-discoverer of the structure of DNA with Francis Crick.

He resigned after making one possibly racist remark. This structure has novel features which are of considerable biological interest. Because what we just described was the article and the day the world first saw the double helical structure of the DNA we have grown accustomed to in the meantime.

So, the autumn of , he went to Cambridge University and joined the group working in the Cavendish Laboratory. Officially — to work on three-dimensional structures of proteins.

Unofficially — to make a discovery which will grant him a Nobel. You think he may have overreacted?Francis, with his interest in theory, had neglected to fasten securely the rubber tubing around his suction pump.

A defining moment for DNA research was the discovery of its structure half a century ago. Ha — see what we did there?

The Double Helix

The reason why James Watson got interested in the study of DNA was not because of the importance of the discovery itself, but because he wanted to be the one to make it. About The Book. Watson was opposed to Healy's attempts to acquire patents on gene sequences, and any ownership of the "laws of nature. Bitter scientific rivalries?
