Molecular Biology Unit Exam Question 1 Consider the following origin of replication that is found on a chromosome. The sequence of region 1 is shown below. Region 1: 5??CTGACTGACA?3? 3??GACTGACTGT?5? 3? 5? 5? 3? Region 1 top ? ori bottom ? a) Within Region 1, which strand will be the template for leading strand synthesis, the top or the bottom? b) If we assume that a lagging strand fragment is made from region 1, what will be its sequence? c) You examine DNA replication in an E. coli mutant, which has a partially defective DNA polymerase. In vitro experiments using the mutant DNA polymerase gives an error rate of 10-3, as compared to the expected error
