He and Sydney Brenner demonstrated that each group of three adjacent bases on a single DNA strand codes for one specific amino acid. He also correctly hypothesized the existence of "transfer" RNA, which mediates between "messenger" RNA and amino acids. After twenty years at Cambridge, with several visiting professorships in the United States, Crick joined the Salk Institute for Biological Studies in La Jolla, California.
