These images are the basis for the conclusions of ... WebAs with the discovery of inheritance and evolution, the story of the discovery of the structure DNA is well known; starting with the Rosalind Franklin’s first image of the double helix in 1952 and then subsequently James Watson’s and Francis Crick’s model of the double helix structure in 1953. However, Oswald Avery had already identified ...

WebOn 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. … WebErwin Chargaff works out the pairing pattern of the bases A, C, G and T. He finds that concentrations of thymine and adenine, and cytosine and guanine, are always found in equal amounts in samples of DNA. This suggested that A always pairs with T and C always pairs with G.
