Donald Burke recently answered questions related to the origins of life for the podcast The Big Electron, hosted by the University of Missouri’s student-run radio station, KCOU 88.1. Burke is an investigator for the Exobiology & Evolutionary Biology element of the NASA Astrobiology Program. His team is providing new insight into whether or not RNA molecules could have served as the principle carriers of genetic information and catalysts in biological reactions for the earliest forms of life on Earth.
