BNFO 300 
DNA - Molecular Biology Through Discovery
Topic: DNA Structure and Function
Fall 2014 

Rationale
DNA is the informational molecule responsible, in most cases, for the propagation of information from one generation to the next. This unit addresses the problem of how that information is propagated.
