Title

crisscrossing Science Episode 34: Jumping Genes, the Barbara McClintock Story

Streaming Media

Abstract

In this episode, Chris Gaiser (professor of biology at Linfield College) and Mike Crosser (professor of physics at Linfield College) discuss the phenomenon of transposable elements of DNA, previously known as jumping genes. It had previously been believed that DNA served as the mostly stable blueprints upon which RNA and then proteins could be formed. However, by studying the statistics of how often traits were passed to offspring in corn, Barbara McClintock was able to discover that DNA is actually somewhat active as well. We now know that DNA will switch places in the chromosome and that some segments will actually replicate themselves.
