Exploring DNA Structure with Cn3D

We thank Charlotte Mulvihill for reviewing the manuscript, Erin Dolan for her analysis of student feedback, Paul Thiessen and Eric Sayers for advice and guidance in using Cn3D, and our student interns, Jeremy Friend, Kate Anderson, Camille Beck, Andrea Porter-Smith, Sam Ryan, Marian Deuker, and Thea Chard, for all of their work in testing and reviewing materials. We also thank Doug Clarkson for his kind advice on performing the statistical analyses.
