Photo 51 is an X-ray based fiber diffraction image of a paracrystalline gel composed of DNA fiber [1] taken by Raymond Gosling, [2] [3] a postgraduate student working under the supervision of Maurice Wilkins and Rosalind Franklin at King's College London, while working in Sir John Randall's group.
Rosalind Franklin joined King's College London in January 1951 to work on the crystallography of DNA. By the end of that year, she established two important facts: one is that phosphate groups, which are the molecular backbone for the nucleotide chains, lie on the outside (it was a general consensus at the time that they were at the inside); and the other is that DNA exists in two forms, a ...
Rosalind Franklin took the X-ray photograph of a DNA fibre that proved key to James Watson and Francis Crick's discovery of the double helix, for which they both won the Nobel Prize for Physiology or Medicine in 1962. Watson revealed in his autobiographic account of the discovery of the structure of DNA, The Double Helix, [136] that he had used ...
Rosalind Franklin was a British molecular biologist who was instrumental in the discovery of the structure of deoxyribonucleic acid in 1951. At King's College London where she applied X-ray diffraction to the study of biological materials , she performed several X-ray radiographs of the DNA.
In 1952, Rosalind Franklin and Raymond Gosling produced a strikingly clear x-ray diffraction pattern indicating a helical form. Using these x-rays and information already known about the chemistry of DNA, James D. Watson and Francis Crick demonstrated the molecular structure of DNA in 1953.

In the book Rosalind Franklin and DNA, author Anne Sayre is very critical of Watson's account. She claims that Watson's book did not give a balanced description of Rosalind Franklin and the nature of her interactions with Maurice Wilkins at King's College, London. Sayre's book raises doubts about the ethics of how Watson and Crick used some of ...
