How bacterial and archaeal dna is organized
WebThe bacterial replicative helicase, exemplified by E. coli DnaB, translocates 5’-3’ along single-strand DNA, placing it on the lagging strand. In contrast, the archaeal and eukaryotic helicases, referred to as MCM (Mini Chromosome Maintenance), translocate 3’-5’ placing them on the leading strand for replication fork advance [13–15].
