Thomas R. Cech

Thomas Robert Cech is Nobel Prize Laureate in Chemistry 1989. Cech’s area of research involves study of process of transcription i.e. how the genetic code in DNA is transcribed to RNA. In 1982 Thomas Cech with his experiment on Tetrahymena thermophilia proved that RNA can act as a catalyst on its own stimulating a chemical reaction. Further research proved his initial findings that RNA can trigger biological reactions which were thought to be catalyzed by proteins.

Thomas Cech received the ACS Pfizer Award 1985, NAS Award in Molecular Biology 1987, Lasker Award 1988, National Medal of Science 1995 and CHF Othmer Gold Medal 2007.
