Paul Zamecnik and his colleagues carried out an experiment to track the fate of radioactive leucine molecules attached to tRNAs (Transport RNAs). In their experiment, they found out that amino acids are transferred from tRNAs to proteins. Paul Zamecnik, an American scientist, played a major role in the early history of molecular biology.
