In 1953, James Watson and Francis Crick published a groundbreaking paper describing the double helix structure of deoxyribonucleic acid (DNA), the molecule that carries genetic information. Their work was based on X-ray diffraction data collected by Rosalind Franklin and Maurice Wilkins, as well as chemical information available at the time.
James D. Watson and Francis Crick are associated with the discovery of:
