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 ...

This was their last communication. Franklin never fully recovered and died on April 16, 1958. [6] Franklin's X-ray crystallography of DNA (dubbed Photo 51) was the key data in the discovery of DNA structure, for which James Watson, Francis Crick and Maurice Wilkins won the 1962 Nobel Prize for Physiology or Medicine. After death, Franklin was ...

The first high quality X-ray diffraction patterns of A-DNA were reported by Rosalind Franklin and Raymond Gosling in 1953. [1] Rosalind Franklin made the critical observation that DNA exists in two distinct forms, A and B, and produced the sharpest pictures of both through X-ray diffraction technique. [2]
Authorities in England announced that a woman who had been previously missing for 52 years was found alive after police recently shared a blurry photo of her at the time of her disappearance.
