Discovery of the structure of DNA. In the 1950s, three groups made it their goal to determine the structure of DNA. The first group to start was at King's College London and was led by Maurice Wilkins and was later joined by Rosalind Franklin. Another group consisting of Francis Crick and James Watson was at Cambridge. The race to discovery. When he returned to Cambridge, Watson shared the new results with Crick and they applied the information to their ball-and-stick models.
