Unformatted text preview: between nitrogenous bases using energy from the 3-P. SSB then binds to each end of the non-single strands keeping them from reacting with each other. Primase then starts replication by bringing complementary bases of RNA to both strands. Once a RNA primer is in place DNA Polymerase III begins to add complementary bases in the 5-3 direction. On the leading strand DNA Polymerase III proceeds progressively towards to replication fork. The lagging strands starts to be replicated in the 5-3 direction. DNA polymerase III also proofreads and fixes its own mistakes. After DNA polymerase III, DNA polymerase I comes through on each strand in the 5-3 direction replacing the RNA primer with DNA bases. Lastly the ligase joins together all the DNA bases by hydrolyzing the O-P making a phosphodiester bond....
