During the 1950s Crick made crucial contributions not only to the study of DNA and the genetic code, but to X-ray structure
analysis of important biological molecules. In this paper, Crick and Alexander Rich, a visiting physical chemist in the Cavendish
laboratory who had studied the structure of RNA with James Watson at the California Institute of Technology, applied X-ray
diffraction theory to deduce the three-dimensional structure of polyglycene II, a synthetic polymer consisting of an array
of polypeptide chains made up solely of the amino acid glycene.
