Mechanisms of DNA replication termination - Harvard University

WebMay 24, 2024 · The termination of DNA replication involves convergence of replication forks, the completion of DNA synthesis, replisome disassembly and the decatenation of daughter DNA molecules. Recent ... WebAs synthesis proceeds, an enzyme removes the RNA primer, which is then replaced with DNA nucleotides, and the gaps between fragments are sealed by an enzyme called DNA ligase. The process of DNA replication can be summarized as follows: DNA unwinds at the origin of replication. New bases are added to the complementary parental strands. WebModel of plasmid RCR. (A) A supercoiled plasmid containing the origin of replication (dso).(B) A RepC protein dimer binds to the dso and nicks the duplex, remaining covalently attached to the 5′-P end.(C) PcrA helicase unwinds the plasmid in complex with RepC producing ssDNA that is further protected from degradation by the SSB protein.The 3′-OH … senior associate director salary boehringer
