![]() ![]() That's all thanks to Photograph 51, an X-ray taken by Franklin in 1952 that depicted a strand of DNA from human tissue. So, what caused the true story behind the discovery of DNA to become so muddled? "This was the biggest surprise for us since it showed that there wasn't this dramatic race like you see in modern competitive labs," Cobb said.Ĭobb and Comfort concluded that Franklin was relaxed in knowing that Crick and Watson knew about her research, writing in their Nature paper that Franklin was "an equal contributor to solving. ![]() In the letter, Cowan invited Crick to a speech given by Franklin about how DNA can take on different forms. The second piece of evidence was a letter written by Pauline Cowan, one of Franklin's colleagues. Given this dynamic, Franklin likely freely shared her knowledge of DNA's spiral structure with Watson and Crick, the Nature paper suggests. While they often worked independently, they also "linked up, confirming each other's work from time to time, or wrestling over a common problem," Bruce wrote.

In the article, Bruce wrote that the group of scientists had divided themselves into teams, one consisting of Wilkins and Franklin, who focused on X-ray analysis of DNA, and the other of Watson and Crick, who were working to solve DNA's structure through a model-based approach. ![]()
