Detailed explanation-1: -stories Giants in genomics: Francis Crick Francis Crick and his American colleague, James Watson, discovered the double helix structure of DNA. For this fundamental finding Francis, James and Maurice Wilkins were awarded the Nobel Prize for Physiology or Medicine in 1962.
Detailed explanation-2: -Chargaff’s realization that A = T and C = G, combined with some crucially important X-ray crystallography work by English researchers Rosalind Franklin and Maurice Wilkins, contributed to Watson and Crick’s derivation of the three-dimensional, double-helical model for the structure of DNA.
Detailed explanation-3: -With the aid of illustrations, Watson and Crick state that their model of DNA consists of two helical strands twisted around each other in a double helix. Each strand, the authors explain, contains a chain of repeating units called nucleotides, where each nucleotide contains a sugar, a phosphate group, and a base.
