Study Offers Insights into Evolutionary Origins of Life; Artificial Enzyme Able to Synthesize RNA

May 17, 2001

In some of the strongest evidence yet to support the RNA world—an era in early evolution when life forms depended on RNA—scientists at the Whitehead Institute for Biomedical Research have created an RNA catalyst, or a ribozyme, that possesses some of the key properties needed to sustain life in such a world.

Whitehead Study Supports Existence of Ancient RNA World

September 16, 1998

For decades, many researchers thought that ribonucleic acid, or RNA, was nothing more than a molecular interpreter that helps translate DNA codes into proteins. But research over the past 15 years, including studies at the Whitehead Institute, has been lending credence to the notion of a so-called “RNA world,” an era in early evolution when all life forms were based on RNA.
