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.
The Linus Pauling Institute still exists, but moved in 1996 from Palo Alto, California, to Corvallis, Oregon, where it is part of the Linus Pauling Science Center at Oregon State University. [ 181 ] [ 182 ] [ 183 ] The Valley Library Special Collections at Oregon State University contain the Ava Helen and Linus Pauling Papers, including ...
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 ...
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 ...
Pauling had deduced this structure from X-ray patterns and from attempts to physically model the structures. (Pauling was also later to suggest an incorrect three chain helical DNA structure based on Astbury's data.) Even in the initial diffraction data from DNA by Maurice Wilkins, it was evident that the structure involved helices.
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. Franklin's identification of the space group for DNA crystals revealed to Crick that the two DNA strands were antiparallel. [207]
Donohue was born in Sheboygan, Wisconsin and studied for his first two degrees at Dartmouth College, where he earned his A.B. in 1941 and his M.A. in 1943. He worked on his PhD under Linus Pauling at the California Institute of Technology (Caltech), earning his doctorate in 1947.
Robert Brainard Corey (August 19, 1897 – April 23, 1971) was an American biochemist, mostly known for his role in discovery of the α-helix and the β-sheet with Linus Pauling. Also working with Pauling was Herman Branson. Their discoveries were remarkably correct, with even the bond lengths being accurate until about 40 years later.
