He is an expert in DNA and the first to propose the correct pairing of the four base molecules of its structure: adenine pairing with thymine and guanine pairing with cytosine. When Watson and Crick learn of this theory, they begin to explore it, too. Eventually, they discover how to make a DNA model that allows for ' 'Chargaff s rules," yet another step in uncovering the mystery of the molecule.

Rosalind Franklin

Rosalind Franklin is trained in crystallography and uses X rays of DNA to try to determine its structure, as opposed to experimental model building. She arrives at the King's College laboratory in Cambridge to work with Maurice Wilkins—who is using the same method to study the acid, but who is not as well trained in the field...
