Crick and Watson already knew the main components of DNA, phosphates, sugars, and four nitrogenous bases: adenine, thymine, cytosine, and guanine. But how did the elements fit together? One clue came from Xray photographs of DNA taken by Rosalind Franklin.

In the early 1950s, the race to discover DNA was on. At Cambridge University, graduate student Francis Crick and research fellow James Watson (b. 1928) had become interested, impressed especially by Pauling's work.

Watson and Crick Discovered the Structure of DNA ... In 1953, James D. Watson and Francis H.C. Crick published a paper in which they proposed a model for the physical and chemical structure of the DNA molecule. According to them, ... In generating their model, Watson and Crick used three main pieces of evidence:

Watson and Crick were not the discovers of DNA. ... From that perspective, Miescher was one of the great scientific geniuses. By the time Watson & Crick came along, virtually all of the facts were in place.

DNA
Although DNA was first isolated by Friedrich Miescher in 1869, it's double helix structure wasn't discovered until 1953 by James Watson and Francis Crick. For their groundbreaking work, Watson and Crick shared the 1962 Nobel Prize in Physiology/Medicine with Maurice Wilkins...
