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 ...
It's 65 years since the structure of DNA was first published, but the woman who made that possible remains unknown to many people. Rosalind Franklin still doesn't get the recognition she deserves ...
On one level, multimedia artist Kate Thompson's work shows the black-and-white visage of Franklin — the late biochemist whose famous "Photo 51" revealed the double-helix structure of life's most ...
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 DNA double helix was discovered in 1953 [4] (with further details in 1954 [5]) based on X-ray diffraction images of DNA (most notably photo 51, taken by Raymond Gosling and Rosalind Franklin [6]) as well as base-pairing chemical and biochemical information.
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]
