Khorana, Har Gobind (1922–2011)
US biochemist who shared the 1968 Nobel Prize in Physiology or Medicine,
with Robert Holley and Marshall Nirenberg,
for discoveries about the way in which genes
determine cell function. They established that most codons,
combinations of three of the four different bases found in DNA
and RNA, eventually cause the inclusion of a
specific amino acid into the cell proteins.
