"Revealing the Backbone Structure of B-DNA from Laser Optical Simulations of Its X-ray Diffraction Diagram. But in 2012, researchers were able to image DNA directly for the first time. It’s difficult to see clearly, but there are ten blobs on each arm of the cross before you reach the large black patch at the top, and this tells you that there are ten bases stacked one on top of the other in each turn of the helix. For example, it was a photo that was labeled as 51, so people call it photo 51. MRC News and Features Producer. The Photograph 51 quotes below are all either spoken by James Watson or refer to James Watson. Instant downloads of all 1372 LitChart PDFs -Graham S. Wilkins condescends to Rosalind even as she calmly and clearly expresses herself. Is Photo 51 in a museum where it can be seen by the public ? She is barred from the lunchroom, a fact which incenses her as she knows that a large part of her profession is not hard science at all, but the connections one makes and the collaborations one becomes part of. Wilkins and his graduate student, Raymond Gosling, later Franklin´s graduate student, collected X-ray diffraction patterns of DNA purified in a way that produced longer fibers than those accessible to Astbury. She pumped hydrogen gas through a salt solution to maintain the targeted hydration of the DNA fibers. My students love how organized the handouts are and enjoy tracking the themes as a class.”, LitCharts uses cookies to personalize our services. The DNA strand was fixed to a support and sealed in a camera, in front of a piece of x-ray film, and then exposed to x-rays for days at a time — you had to hope the sample didn’t move! ", Lucas, Amand A. This passage highlights the personal and professional subterfuge fueling the “race” in which all four scientists have found themselves. Rosalind and Wilkins’s animosity toward each other has become intensely personal and vitriolic, as their argument in this passage shows. The original text plus a side-by-side modern translation of. He also knows that as long as he and Rosalind are spatting and sparring, they don’t stand a chance of winning the “race”— he is increasingly eager to do. [13] Likewise, Gosling's work was not cited by the prize committee. Photo 51 is an X-ray diffraction image of a paracrystalline gel composed of DNA fiber taken by Raymond Gosling, a graduate student working under the supervision of Rosalind Franklin in May 1952 at King's College London, while working in Sir John Randall 's group. Of course the structure was right — it was too beautiful not to be. Again, the other characters function like a chorus in this passage as they debate whether Rosalind’s fate was sealed in a single instant, or whether her choices and actions still could have changed the course of her life. Randall, the head of the group, had asked Gosling to share all his data with Wilkins. The unit was then part of the King’s College campus on the Strand in London and was run by Sir John Randall, who had turned some of the university’s physics department over to studying biological problems. Crick, though, harbors a quiet admiration for Rosalind’s personal and professional conduct and for the things she values above her own glorification. Crick and Watson want to help humanity, to be sure—but this passage shows that they are more motivated by the prospect of science as a means to personal glory and professional immortality. Published in the UK by Chatto & Windus (, "The structure of sodium thymonucleate fibres. Their ambition to become the first to create a working model of DNA, coupled with Rosalind’s stubbornness, leads them to gain notoriety as the first to complete and discover the DNA model. In this case it’s 3.4 Ångstroms, a unit of measurement equivalent to 0.1 nanometre. This group of characters—perhaps because of the fortuitous, chaotic moment in which they live—is obsessed with fate and time, and how those forces have impacted their lives and those of their colleagues. Scientists began collecting X-ray diffraction patterns of DNA in the 1930s before they confirmed that DNA contained genes. After exposing the DNA fibers to X-rays for a total of sixty-two hours, Franklin collected the resulting diffraction pattern and labeled it Number 51 that became Photo 51.

Watson and Crick proposed that the DNA strands needed to unwind and separate in order to replicate. Teachers and parents! Rosalind is upset and offended by Wilkins’s subtle suggestion that she take care of their collective materials maintenance, a menial task that is beneath her. Teachers and parents! At the time of Astbury´s experiments, scientists had determined the chemical composition of DNA. I’m really interested in the role of experts in our society. Wilkins hasn’t realized that his actions have consequences—and that he can’t take back betraying Rosalind in exchange for the fame and renown partnering with Watson and Crick afforded him. Detailed explanations, analysis, and citation info for every important quote on LitCharts. So what are we actually looking at when we look at photo 51?

He does not take her seriously because she is a woman. Photo 51 is an X-ray diffraction image of a paracrystalline gel composed of DNA fiber [1] taken by Raymond Gosling,[2][3] a graduate student working under the supervision of Rosalind Franklin in May 1952 at King's College London, while working in Sir John Randall's group. While Franklin obtained Photo 51 in May 1952, she did not complete her analysis of Photo 51 until early 1953. Wilkins tells her about Watson and Crick’s model and laments that he and Rosalind have lost the race, but Rosalind insists the opposite is true: the whole world, she says, has won. These days we take thousands of images from different angles and digitally build up a 3D image of the structure. On 6 May 1952, at King´s College London in London, England, Rosalind Franklin photographed her fifty-first X-ray diffraction pattern of deoxyribosenucleic acid, or DNA. ", Marsh, Richard E.

The X shape is not made of continuous lines. Watson was surprised that she accepted the correctness of their model immediately upon seeing it — it must have been because she could see that it fitted so well with all of her evidence.
