For the Mars rover named after her, see Rosalind Franklin (rover).

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 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 1962, they will share the Nobel Prize in Medicine with Maurice Wilkins, who publishes X-ray crystallography results for DNA in the same issue of Nature in 1953. [5] The third related article published at the same time is by Rosalind Franklin and Raymond Gosling, on "Molecular Configuration in Sodium Thymonucleate". [6] [7]
1952: an X-ray diffraction image of DNA was taken by Raymond Gosling in May 1952, a student supervised by Rosalind Franklin. [30] 1953: DNA structure is resolved to be a double helix by James Watson, Francis Crick and Maurice Wilkins. [31] 1955: Alexander R. Todd determined the chemical makeup of nitrogenous bases.
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.
Of the currently revealed female nominees, the physiologists Nettie Stevens, Frieda Robscheit-Robbins, Rosalind Franklin, Miriam Michael Stimson, Louise Pearce, Virginia Apgar, Hattie Alexander and Alice Catherine Evans were not included. The most number of female nominees was in the field of literature.
Norman Simmons (1915–2004), US DNA research pioneer, who donated pure DNA to Rosalind Franklin in the prelude to the double helix discovery; Piotr Słonimski (1922–2009), Polish-Parisian yeast geneticist, pioneer of mitochondrial heredity; William S. Sly (born 1932), US biochemical geneticist, mucopolysaccharidosis type VII (Sly syndrome)
