TWiV 66: Reverse transcription

17 January 2010 by Vincent Racaniello

Hosts: Vincent Racaniello and Dickson Despommier

Vincent and Dickson continue virology 101 with a discussion of information flow from RNA to DNA, a process known as reverse transcription, which occurs in cells infected with retroviruses, hepatitis B virus, cauliflower mosaic virus, foamy viruses, and even in uninfected cells.
