Detailed explanation-1: -At King’s College London, Rosalind Franklin obtained images of DNA using X-ray crystallography, an idea first broached by Maurice Wilkins.
Detailed explanation-2: -Maurice Wilkins and Rosalind Franklin had obtained high-resolution X-ray images of DNA fibers that suggested a helical, corkscrew-like shape.
Detailed explanation-3: -At King’s College in London, Rosalind Franklin and Maurice Wilkins were studying DNA. Wilkins and Franklin used X-ray diffraction as their main tool–beaming X-rays through the molecule yielded a shadow picture of the molecule’s structure, by how the X-rays bounced off its component parts.
Detailed explanation-4: -On 6 May 1952, at King´s College London in London, England, Rosalind Franklin photographed her fifty-first X-ray diffraction pattern of deoxyribosenucleic acid, or DNA.
Detailed explanation-5: -This X-ray diffraction picture of a DNA molecule was Watson’s inspiration (the pattern was clearly a helix). Using Franklin’s photograph and their own data, Watson and Crick created their famous DNA model.
