How did James Watson discover DNA?

James Watson did not discover DNA. The discovery of DNA is attributed to Friedrich Miescher in 1869. Miescher, a Swiss biochemist, isolated a substance from the nuclei of white blood cells that he called "nuclein." Further research revealed that nuclein was made up of nucleic acids, and eventually, the structure of DNA was discovered by Rosalind Franklin and Maurice Wilkins using X-ray crystallography in 1953. Watson and Francis Crick used this data to build a model of the DNA double helix in 1953, for which they received the Nobel Prize in Physiology or Medicine in 1962.
