James Watson and Francis Crick are credited with describing the double helix structure of deoxyribonucleic acid (DNA) in 1953, publishing their findings in the journal Nature. Their model was based on X-ray diffraction data obtained by Rosalind Franklin and Maurice Wilkins, and they also incorporated information from Erwin Chargaff about base pairing rules. They, along with Maurice Wilkins, were awarded the Nobel Prize in Physiology or Medicine in 1962 for this discovery.
