View source for Genetics (Biological)

There have been a lot of lectures that touch on genes, genomes, DNA, ...etc. I thought the non-biologists might be interested in a little bit of background on molecular biology, focusing on genetics. It'd be nice to keep things informal, but basic topics I think would be helpful are:
* classical genetics and mapping (genetics before we knew about DNA)
* gene expression (and how it's regulated)
* difference between genetic networks and biochemical networks
* epigenetics, relating to Lamarkian evolution and stem cells

It could be a simple cartoon format tutorial or just be a discussion. Anybody interested? - Will L.
