The double helix structure of DNA discovered in 1953 explained the basic mechanism for how our genetic information can be inherited through replication. But, we've since found that those genes have on/off switches. Understanding how our genes are turned on and off has been complicated partly due to the compacting of DNA with proteins (the histones) into chromatin. Dr. Song Tan has spent years studying chromatin using advanced imaging technology and he and his colleagues have made some big discoveries looking at molecular sized objects. He is joined by Mark Kozak, Executive Director of Telluride Science and by Dr. Richard Kriwacki of St. Jude's Children's Research Hospital. Podcast hosts: veteran broadcast journalists Judy Muller and George Lewis.
