    en.wikipedia.org/wiki/Molecular_Structure_of...

    In 1951, Pauling published the structure of the alpha helix, a fundamentally important structural component of proteins. In early 1953, Pauling published a triple helix model of DNA, which subsequently turned out to be incorrect. [3] Both Crick, and particularly Watson, thought that they were racing against Pauling to discover the structure of DNA.

    en.wikipedia.org/wiki/Linus_Pauling

    When it was learned at the Cavendish Laboratory that Pauling was working on molecular models of the structure of DNA, James Watson and Francis Crick were allowed to make a molecular model of DNA. They later benefited from unpublished data from Maurice Wilkins and Rosalind Franklin at King's College which showed evidence for a helix and planar ...

    Some of these structures were proposed during the 1950s before the structure of the double helix was solved, most famously by Linus Pauling. Non-helical or "side-by-side" models of DNA were proposed in the 1970s to address what appeared at the time to be problems with the topology of circular DNA chromosomes during replication (subsequently ...

    Narrated by Jeff Goldblum, it features Watson, Wilkins, Gosling and Peter Pauling (son of Linus Pauling). [27] A play entitled Photograph 51 by Anna Ziegler focuses on the role of X-ray crystallographer Rosalind Franklin in the discovery of the structure of DNA. [28] [29] This play won the third STAGE International Script Competition in 2008. [30]

    The chemical structure of DNA is insufficient to understand the complexity of the 3D structures of DNA. In contrast, animated molecular models allow one to visually explore the three-dimensional (3D) structure of DNA. The DNA model shown (far right) is a space-filling, or CPK, model of the DNA double helix. Animated molecular models, such as ...

    en.wikipedia.org/wiki/DNA:_The_Story_of_Life

    It covered the discovery of DNA in 1953. [1] Maurice Wilkins and his involvement with the Manhattan Project, speaking in his university office in London; Linus Pauling's son Peter, of Caltech, now lived in Wales; Linus Pauling approached the discovery of the structure of DNA in a much more methodical rigid manner, perhaps in a plodding way, and Pauling was never one to take the same un-thought ...

    They are also competing with other scientists in the UK, and with international scientists such as American Linus Pauling. The film manages to convey the loneliness and competitiveness of scientific research but also educates the viewer about how DNA's structure was discovered. It explores the tension between the patient, dedicated laboratory ...

    This photo was given to Watson and Crick by Maurice Wilkins and was critical to their obtaining the correct structure of DNA. Franklin told Crick and Watson that the backbones had to be on the outside. Before then, Linus Pauling, and Watson and Crick, had erroneous models with the chains inside and the bases pointing outwards.
