Ch. 16 The Molecular Basis of Inheritance

Ch. 16 The Molecular Basis of Inheritance. DNA is the Genetic Material. Experiments with bacteria and with phages provided the first strong evidence that the genetic material is DNA Watson and Crick deduced that DNA is a double helix and built a structural model. .
