Thomas Cech

Thomas Robert Cech (born December 8, 1947) is an American chemist who shared the 1989 Nobel Prize in Chemistry with Sidney Altman for their discovery of the catalytic properties of RNA.

[3] As president of Howard Hughes Medical Institute, he promoted science education, and he teaches an undergraduate chemistry course at the University of Colorado.

In junior high school, he knocked on the doors of geology professors at the University of Iowa, and asked them to discuss crystal structures, meteorites and fossils.

[4] In 1975, Cech completed his PhD in chemistry at the University of California, Berkeley and in the same year, he entered the Massachusetts Institute of Technology where he engaged in postdoctoral research.

Cech is the author of The Catalyst: RNA and the Quest to Unlock Life’s Deepest Secrets, published in June 2024.

In 1982, Cech became the first to show that RNA molecules are not restricted to being passive carriers of genetic information – they can have catalytic functions and can participate in cellular reactions.

[8] The active site protein subunits of telomerase comprise a new class of reverse transcriptases, enzymes previously thought to be restricted to viruses and transposable elements.
