Present an overview of two classical experiments that demonstrated that DNA is the genetic material. Can RNA be the genetic material? Explain.

(1) Transformation in bacteria (Griffith through Avery et al.); see appropriate
figures in the text. (2) The Hershey and Chase experiment in bacteriophage; see appropriate figures in the text. Yes, RNA can be the genetic material as
described for the Tobacco Mosaic Virus (TMV), retroviruses, and many others.
