Chapter 16: The Molecular Basis of Inheritance Overview: Life?s Operating Instructions Watson and Crick introduced the double-helical model for the structure of DNA DNA is the substance of inheritance encoded in chemical language of DNA and reproduced in all the cells of your body it is DNA that directs the development of many different types of traits Concept 16.1: DNA is the genetic material The Search for the Genetic Material: Scientific Inquiry the role of DNA in heredity was first worked out by studying bacteria and the viruses that infect them Evidence That DNA Can Transform Bacteria Griffith worked with a pathogenic and nonpathogenic strain

Practice Problems for Molecular Biology, Session 2: DNA Replication Question 1 ATP ? a) Box the part that is added to a growing chain of nucleic acid. b) Star the atom(s) that can form a hydrogen bond with the complementary nitrogenous base. c) Circle the part of the molecule that decreases the stability of RNA as compared to DNA. d) Draw an arrow to the part of this molecule that you would modify to prevent further elongation. Indicate what change you would make next to the arrow drawn. Question 2 Consider the following origin of replication that is found on a chromosome. The sequence of region 1 is shown. Region 1: 5??CTGACTGACA?3?
