DOUBLE HELIX — TWO SCIENTISTS AT CAMBRIDGE UNIVERSITY ON FEB. 28, 1953 DETERMINED the double-helix structure of DNA, the molecule containing human genes. However, the scientists James D. Watson and Francis H.C. Crick received significant assistance from another DNA researcher named Rosalind Franklin, who was omitted from the announcement and from the Nobel Prize that was awarded later. DNA— short for deoxyribonucleic acid— was discovered in 1869 but, its vital role in determining genetic inheritance wasn’t demonstrated until 1943. In the early 1950s, Watson and Crick were only two of many scientists who were trying to figure out DNA’s structure and were often in competition with each other. Watson produced a best-selling book, titled “The Double Helix,” but it turned out to be at the expense of their friendship, as Crick claimed he misrepresented their collaboration.
Another scientist, Maurice Wilkins, showed Watson and Crick Franklin’s x-ray photography just before the duo made their discovery. Crick and Watson shared their 1962 Nobel Prize with Wilkins. However, Franklin had died of cancer four years earlier and never learned how significant her photography was to the discovery.
