Rosalind Franklin, Mother of the DNA structure
Monday, October 29th, 2007Who? James Watson.
Oh, once again, what did you say? James Watson, father of DNA structure.
Oh.. are you kidding? come on guys… every body should know that it was not (James) Watson and (Francis) Crick who discovered the DNA helix structure, instead, it was Rosalind Franklin and her student, Raymond Gosling, who first discovered the double helix structure of (sodium salt) DNA.
This X-ray diffraction image of DNA, worldknown as photograph 51, was taken by Rosalind Franklin while she was working at King’s College London in January 1953. Almost at the same time in February 1953 Francis Crick and James D. Watson of the Cavendish Laboratory in Cambridge University started to build a model of the B form of DNA using similar data to that available to the team at King’s. Model building had been applied successfully in the elucidation of the structure of the alpha helix by Linus Pauling in 1951. However, this theoretical model was opposed by Rosalind, taking the view that building a model was only to be undertaken after the structure was known. Watson and Crick then indirectly obtained a prepublication version of Franklin’s DNA X-ray diffraction data (without her knowledge), and a prepublication manuscript by Pauling and Corey, giving them critical insights into the DNA structure. Later on, it was known that Maurice Wilkins had shown Watson the photograph-51 without Rosalind Franklin’s knowledge. This led Rosalind a decision to leave King’s College London. Wilkins expressed his great regret afterward.
There is no doubt that Rosalind Franklin’s experimental data were used by Crick and Watson to build their model of DNA in 1953. Unfortunately, because Rosalind Franklin had died in 1958 she was not eligible for nomination to the Nobel Prize subsequently awarded to Crick, Watson, and Wilkins in 1962.
However, Rosalind Franklin will always be remembered as one of the greatest (women) in science, along with Madame Curie and Guppert-Meyer, while Watson, with his nasty statements (the last he mentioned that Black people are genetically inferior), i believe, more will be remembered as a man who experiences a post power syndrome.
