Episode 11: Mutations … and Porsches

This episode is about mutations especially types of mutations and their effects on proteins, genetic variation and viral antigenic drift and also answers some great questions asked by listeners about a range of things that often confuse students, such as why we are not still immune to a virus that has undergone antigenic shift, or why we have both NK cells and Tc cells (CTLs) when they both seem to do the same thing ... and more.
