![]() ![]() ![]() When it had been decided that Franklin would leave King's College, Gosling showed the photograph to Maurice Wilkins (who would become Gosling's advisor after Franklin left).Ī few days later, Wilkins showed the photo to James Watson after Gosling had returned to working under Wilkins' supervision. Use in discovering structure of DNA Īccording to Raymond Gosling's later account, although photo 51 was an exceptionally clear diffraction pattern of the "B" form of DNA, Franklin was more interested in solving the diffraction pattern of the "A" form of DNA, so she put Gosling's photo 51 to the side. It was critical evidence in identifying the structure of DNA. The image was tagged "photo 51" because it was the 51st diffraction photograph that Franklin had taken. Photo 51 is an X-ray based fiber diffraction image of a paracrystalline gel composed of DNA fiber taken by Raymond Gosling, a graduate student working under the supervision of Rosalind Franklin in May 1952 at King's College London, while working in Sir John Randall's group. ![]()
