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 ...

The double-helix model of DNA structure was first published in the journal Nature by James Watson and Francis Crick in 1953, [6] (X,Y,Z coordinates in 1954 [7]) based on the work of Rosalind Franklin and her student Raymond Gosling, who took the crucial X-ray diffraction image of DNA labeled as "Photo 51", [8] [9] and Maurice Wilkins, Alexander Stokes, and Herbert Wilson, [10] and base-pairing ...
Photograph 51 is a play by Anna Ziegler. Photograph 51 opened in the West End of London in September 2015. [1] The play focuses on the often-overlooked role of X-ray crystallographer Rosalind Franklin in the discovery of the double helix structure of DNA while working at King's College London.
Rosalind Franklin: The Dark Lady of DNA is a biography of Rosalind Franklin, a scientist whose work helped discover the structure of DNA. [1] [2] It was written by Brenda Maddox and published by HarperCollins in October 2002. [3] A play based in part on the book, Photograph 51 written by Anna Ziegler, was staged in London in 2015 starring ...
A look at the lives of Dr. Susan Smith McKinney Steward, the first Black female doctor in New York, and her sister Sarah J. S. Tompkins Garnet, the first Black female principal in NYC.
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] The first calculations of the Fourier transform of an atomic helix were reported one year earlier by Cochran, Crick and Vand, [ 3 ] and were followed in 1953 by the ...
