WebWatson and Crick; x-ray diffraction images of DNA helix Chargaff discovered that the A-T bond has the same width as the G-C bond. What implication does this have for the structure of the DNA molecule? It means that the molecule will vary in width as you move down its length, depending on the number of A-T and G-C nucleotides. WebDNA was first discovered in the mid-19th century, but its function remained a mystery. In the early 1950s two scientists, Rosalind Franklin and Maurice Wilkins, studied DNA using X-rays....
