“Wielding imaging techniques such as X-ray crystallography, which is what Rosalind Franklin used to find evidence of the structure of DNA, structural biologists try to discover the three-dimensional shape of molecules. Linus Pauling worked out the spiral structure of proteins in the early 1950s, which was followed by Watson and Crick’s paper on the double-helix structure of DNA.”
