DNA: Secret of Photo 51 DVD
PRODUCT DETAILS
On April 25, 1953, James Watson and Francis Crick published their ground breaking discovery of the double helix structure of DNA, the molecule essential for passing on our genes and the “secret of life.” But their crucial breakthrough depended on the pioneering work of another biologist - Rosalind Franklin. She would never know that Watson and Crick had seen a crucial piece of her data without her permission. This was an X-ray image, “Photo 51,” that proved to be a vital clue in their decoding of the double helix. 50 years later, NOVA investigates the shocking truth behind one of the greatest scientific discoveries and presents a moving portrait of a brilliant woman in an era of male-dominated science. 56 minutes. Grade 6 and up.
