When you finish this chapter, you should: Understand semi-conservative mode of DNA replication; know the difference between conservative, semi-conservative and random modes of DNA replication; understand the Messelson and Stahl experiments; know that DNA replication is bi-directional and semi-discontinuous; know the functions of the three DNA polymerases in E. coli;. | Chapter 20 DNA Replication and Repair Replication is bidirectional DNA Replication is Semidiscontinuous Okazaki Fragments DNA Polymerase III is a Multisubunit Enzyme DNA Polymerase III Subunit Organization DNA Replication is a Processive Process.
