Sadly, Maurice Wilkins and Rosalind Franklin, working in the same field, in the same “ the relationship between me and Rosalind began on an extremely. Maurice Wilkins and Rosalind Franklin discovered the structure of DNA at King's. Newly found letters between Francis Crick and Maurice Wilkins illuminate the exasperation and strained relationships at the heart of one of the greatest College London alongside X-ray crystallographer Rosalind Franklin.

The biological functions of A-DNA were only discovered 60 years later. Franklin chose the data rich "A" form while Wilkins selected the "B" form [60] [61] because, according to his self-written biography, Wilkins' preliminary pictures had hinted it might be helical. The X-ray diffraction pictures, including the landmark Photo 51taken by Franklin at this time have been called by John Desmond Bernal as "amongst the most beautiful X-ray photographs of any substance ever taken".

She must have mailed them while the Cambridge team was building their model, and certainly had written them before she knew of their work. He then published an evaluation of the draft's close correlation with the third of the original trio of 25 April Nature DNA articles. Since Wilkins was not in his office, Watson went to Franklin's lab with his urgent message that they should all collaborate before Pauling discovered his error.

The unimpressed Franklin became angry when Watson suggested she did not know how to interpret her own data. Watson hastily retreated, backing into Wilkins who had been attracted by the commotion. Much of their data was derived directly from research done at King's by Wilkins and Franklin. Franklin's research was completed by Februaryahead of her move to Birkbeck, and her data was critical. She took the view that building a model was to be undertaken only after enough of the structure was known.

Photographs of her Birkbeck work table show that she routinely used small molecular models, although certainly not ones on the grand scale successfully used at Cambridge for DNA. In the middle of FebruaryCrick's thesis advisor, Max Perutzgave Crick a copy of a report written for a Medical Research Council biophysics committee visit to King's in Decembercontaining many of Franklin's crystallographic calculations.

By 28 FebruaryWatson and Crick felt they had solved the problem enough for Crick to proclaim in the local pub that they had "found the secret of life". Wilkins came to see the model the following week, according to Franklin's biographer Brenda Maddox on 12 March, and allegedly informed Gosling on his return to King's.

Franklin did modify this draft later before publishing it as the third in the trio of 25 April Nature articles.

On 18 March, [82] in response to receiving a copy of their preliminary manuscript, Wilkins penned the following: As a result of a deal struck by the two laboratory directors, articles by Wilkins and Franklin, which included their X-ray diffraction data, were modified and then published second and third in the same issue of Nature, seemingly only in support of the Crick and Watson theoretical paper which proposed a model for the B form of DNA.

She is reported to have commented, "It's very pretty, but how are they going to prove it? As such, her response to the Watson-Crick model was in keeping with her cautious approach to science.

At first mainly geneticists embraced the model because of its obvious genetic implications. Her new laboratories were housed in 21 Torrington Square, one of a pair of dilapidated and cramped Georgian houses containing several different departments; Franklin frequently took Bernal to task over the careless attitudes of some of the other laboratory staff, notably after workers in the pharmacy department flooded her first-floor laboratory with water on one occasion.

Despite the ARC funding, Franklin wrote to Bernal that the existing facilities remained highly unsuited for conducting research " Her meeting with Aaron Klug in early led to a longstanding and successful collaboration.

Rosalind Franklin :: DNA from the Beginning

They soon discovered published in that the covering of TMV was protein molecules arranged in helices. When she graduated, Franklin was awarded a research scholarship to do graduate work. She spent a year in R. Norrish 's lab without great success. Norrish recognized Franklin's potential but he was not very encouraging or supportive toward his female student.

CURA was a young organization and there was less formality on the way research had to be done. Franklin worked fairly independently, a situation that suited her. Franklin worked for CURA until and published a number of papers on the physical structure of coal. Franklin's next career move took her to Paris.

An old friend introduced her to Marcel Mathieu who directed most of the research in France. He was impressed with Franklin's work and offered her a job as a "chercheur" in the Laboratoire Central des Services Chimiques de l'Etat. Here she learned X-ray diffraction techniques from Jacques Mering. What would have happened if Wilkins and Franklin had got on? Randall decided to recruit a new researcher with greater expertise in this technique, Rosalind Franklin. As far as Wilkins understood it, Franklin was to work with him, or even be his assistant; the appointment letter to Franklin from Randall made clear that she alone would be working on the structure of DNA.

John Randall Whether Randall wanted to kick Wilkins up the backside, or to get the two researchers to compete is not clear; whatever the case, the result was catastrophic — as well as the structural misunderstanding of who did what and who was in charge, there was a major clash of personality.

The introverted Wilkins became even more withdrawn, and the outgoing and argumentative Franklin became frustrated. Wilkins and Franklin were separated, each working on a different form of the DNA molecule — Franklin worked on the drier A form, which gave misleadingly precise X-ray images, while Wilkins worked on the biologically more significant B form, which gave blurrier images.

They spent much of this way, not talking to each other, not collaborating, not exchanging ideas.

Letters shed light on bitter rivalries behind discovery of DNA double helix

These data were what Watson and Crick used to build their double helix structure. They — or rather. Crick — could see the implications of those data where Franklin had not because Crick had recently developed a mathematical procedure for turning the 2-dimensional data produced by a molecular helix into a 3-dimensional model; he had published this in Nature in October
