Page 2Letter from D. P. Riley to Linus Pauling. May 2, 1953.
Riley writes that, due to budget restraints, he is being compelled to apply for a
position at Queen's University in Kingston, Ontario, Canada. As such, Riley asks
that Pauling please provide an informal letter of recommendation. He also discusses
the details of his current research on the structure of proteins as well as the on-going
debate over the correct structure of DNA. Riley surmises that "of the two [DNA structures],
I must say that I prefer [Watson and Crick's] as it is more flexible and labile [than
the Pauling-Corey model]; also the phosphate groups are on the outside and there seems
to be good chemical evidence for this." Riley does, however, note that the Pauling-Corey
model is "most convincing from the packing point-of-view" and concludes that both
structures might possibly exist in differing circumstances.
