PowerPoint Slides for Chapter 1: Heritable Material by A. Malcolm Campbell, Laurie J. Heyer, & Christopher Paradise 1.3 Can you prove protein is NOT the heritable material? Integrating Concepts in Biology Title Page Copyright © 2015 by AM Campbell, LJ Heyer, CJ Paradise. All rights reserved.

Biology Learning Objectives Interpret data showing that DNA is the heritable material and protein is not. Evaluate experimental design and analyze data from research on DNA as molecular information. ELSI Learning Objectives Critique the common misconceptions about DNA evidence in trials. Argue whether other people have the right to access your DNA information.
