Canadian-American biochemist Sidney Altman shared the 1989 Nobel Prize in Chemistry for his discovery of ribozymes, or catalytic RNA. These RNA molecules can perform chemical reactions like those typically carried out by enzymes. This finding challenged the prevailing dogma that only proteins could act as catalysts in biological systems.
