He discovered transfer RNA, a crucial molecule in the synthesis of proteins in the cell, and antisense therapy, in which strands of DNA or RNA are used to block the activity of genes. Most scientists are fortunate if they can make one major discovery in their lifetime. Dr. Paul Zamecnik made two, each of which should have won him a Nobel Prize.
