The document discusses the mechanisms of DNA replication, focusing on the roles of leading and lagging strands, the formation of Okazaki fragments, and the function of various DNA polymerases in prokaryotes and eukaryotes. It highlights key processes such as the initiation of replication, the action of primase and helicase, as well as the proof-reading capabilities of DNA polymerase III. Additionally, it compares prokaryotic and eukaryotic replication, emphasizing the differences in replication structures, Okazaki fragment lengths, and the importance of telomerase in eukaryotic DNA replication.
