Ribozymes: Hearkening Back to an RNA World
Jeffrey Perkel | Sep 15, 2002 | 9 min read
Illustration: Ned Shaw LIKE MOLECULAR TOY-MAKERS, ribozyme researchers create tools with evolutionary, diagnostic, and therapeutic applications. Nearly 20 years ago, Tom Cech and Sidney Altman discovered that some naturally occurring RNAs could perform enzymatic reactions, earning these researchers the 1989 Nobel Prize in chemistry. Scientists have now identified several examples of RNA enzymes, or ribozymes. Most make or break the phosphodiester bonds in nucleic acid backbones, but some
