Episode XXXIV: Jumping Genes, the Barbara McClintock story

November 27, 2017

In this episode, Chris and Mike 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.
