Although Dr. Paul Zamecnik was nominated repeatedly for the Nobel and rumors circulated each year that he would finally receive it, the prize never came. He did, however, win a 1996 Lasker Award, the prestigious American prize that is often a precursor of the Nobel, and the National Medal of Science in 1991.

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.
Working with Dr. Mahlon Hoagland, he discovered transfer RNA, a crucial molecule in the synthesis of proteins in the cell. Later, he invented the idea of antisense therapy, in which strands of DNA or RNA are used to block the activity of genes -- a concept that is now being turned into a new class of drugs for cancer, HIV and a host of other diseases.
Zamecnik died of cancer Oct. 27 at his home in Boston. He was 96.
