Rosalind Franklin and DNA best evidence for the structure of DNA. For the discovery of the correct chemical structure of DNA, the Nobel Prize in Physiology or Medicine 1962 was shared by her colleagues and close researchers James Watson, Francis Crick and Maurice Wilkins; she died four years earlier in 1958 making her inelligible for the award. Rosalind Franklin joined the 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
Raymond Gosling of x-ray diffraction photography of DNA and obtained at the time the sharpest diffraction images of DNA. Gosling made the X-ray diffraction image of DNA known as "Photograph 51". This work led directly to the 1962 Nobel Prize for Physiology or Medicine being awarded to Francis Crick, James D. Watson and Maurice Wilkins. Gosling was the co-author with Franklin of one of the three DNA double helix papers published in "Nature" in April 1953. His other King's colleagues included Alex Stokes and Herbert Wilson. Gosling briefly remained at King's College following the completion of his thesis in 1954 before lecturing
