Secret of Photo 51 (#3009)

April 2003 marks the 50th anniversary of one of science's great milestones -- the discovery of the double-helix structure of DNA. This "cracking" of life's essential molecular "cookbook" was credited to three British scientists, James Watson, Francis Crick and Maurice Wilkins. But their breakthrough would have been impossible without the work of a brilliant molecular biologist and crystallographer named Rosalind Franklin. In 1962, when the three men were awarded a Nobel Prize for their discovery, Franklin's name wasn't even mentioned. Tragically, she had died of cancer, four years earlier at age 37. The cancer was probably the result of radiation exposure she suffered while taking the x-ray photographs of the DNA that were directly responsible for decoding its structure. NOVA investigates the life of Rosalind Franklin and her unsung contribution to one of science's greatest discoveries. Through eyewitness accounts and the replication and re-enactments of numerous experiments, viewers will see the tragic story of a brilliant young woman and the male-dominated race to find the scientific secret of life.
