Thomas Robert Cech Born 8 Dec 1947.American biochemist and molecular biologist who, with Sidney Altman, was awarded the 1989 Nobel Prize for Chemistry for their discoveries concerning RNA (ribonucleic acid). Prior to Cech's research on RNA, most scientists believed that proteins were the only catalysts in living cells. Discoveries by both Cech and Altman overturned the notion that RNA is merely a genetic messenger - an intermediate in the synthesis of proteins from DNA. Cech showed that RNA could have an independent catalytic function, a "ribozyme", aiding a chemical reaction without being consumed or changed. This discovery had major implications for genetic engineering as well as for understanding how life arose.
