This was James Watson's comment on first glimpsing Photograph 51, the famous Franklin's relationship with Wilkins was famously fractious. Rosalind herself realised that she just didn't pick it up and run with it." It was data of Franklin's which Maurice Wilkins innocently showed to James view, that Rosalind Franklin's relationship with the three men becomes of the greatest importance. . Almost Nobody Aces This s Car Quiz - Can You?. When Franklin arrived at King's College in , J. T. Randall's biophysics program However, there was a shift in research priorities after Maurice Wilkins, the and confused by this, Wilkins still expected that their relations might improve.

Watson, only 23 inwas at Cambridge as a postdoctorate fellow in biology with limited knowledge of chemistry. He was at the Cambridge lab to learn crystallography.

Between and January Franklin reasoned through her precise X-ray diffraction images that: In late she recorded an especially clear X-ray diffraction image that her col- league, Maurice Wilkins, later showed to Watson in January without telling Franklin or asking her permission. Franklin and Wilkins did not always communicate well, so his actions were perhaps not surprising.

He was so excited that he returned to his lab to draw up plans for models that the machine shop would construct out of sheet metal and wire. In building their models, Watson and Crick had to find the answers to several questions.

How many strands did the helix have? Which direction did the strands run?

Rosalind Franklin Couldn't Deal With People

Were they on the inside or the outside? How were the four chemical bases arranged? First, they tried using two strands, putting them in the center of the model with the bases on the outside; however, this did not produce a chemically acceptable structure.

Next, they played around with the shapes of the four bases, using paper models and combining them in different ways. Finally, they visualized a structure that solved the puzzle: If two of the bases were bonded in pairs G with Cthey took up the same space as the other pair A with T. Hence, they could be arranged like steps on a spiral staircase inside of two strands of sugar-phosphates running in opposite directions. These insights occurred to Crick and Watson between February 4 and February 28, when they announced at lunch in their usual pub that they had found the secret of life.

She had died from ovarian cancer at the age of 37 on April 16,in London. And in any case, she may not have had the chance for the award had she been alive. Crick and Watson never told Franklin that they had used her images She was mentioned only in passing by Crick and Watson in Nature.

Nor did Watson explain this in his popular account of their discovery, The Double Helix If she had survived, would she have been acknowledged and shared in the prize? They simply included this sentence: Then the cell uses each strand as a template to assemble another DNA strand from free-floating complementary bases: A picks up T, while C picks up G.

This would result in two identical DNA molecules, one a copy of the other. Occasional mistakes in copying enable evolution to occur and each organism to be unique. Though Franklin and Watson never became friendly, Crick and his wife welcomed Franklin into their home while she was being treated for ovarian cancer. Franklin died of cancer in Though genetics likely played a part in her illness, her work with crystal x-ray diffraction, which involved constant exposure to radiation, did not help.

She is not the first woman in science to risk her health for her research. Marie Curie died from aplastic anemia, which has been tied to radiation exposure.

Many of Curie's personal belongings, including her cookbooks, are too radioactive to handle even today. Keystone, Getty Images The first, of course, would have been awarded with Watson, Crick, and Wilkins, had they been made to share credit with her.

Pierre Curie had to ask the Nobel Committee to add his wife to the nomination in As for the second, chemist Aaron Klug won the prize incarrying on work he and Franklin had started on viruses inafter she left King's College.

Jeff Goldblum played Watson. Inplaywright Anna Ziegler premiered a one-act about Franklin called Photograph While Kidman got much praise from critics for her turn as Franklin in Photograph 51, Maurice Wilkins' friends and former colleagues have taken exception to a scene where Wilkins takes a photograph—the titular Photo 51, which showed evidence of DNA's structure—from Franklin's desk when she isn't there, saying he would never have done something so dishonorable.

Inthe West End production's director, Michael Grandage, told The Hollywood Reporter that he hopes to turn the play into a film—with Kidman reprising the role.
