WebbDNA replication in prokaryotes and eukaryotes happens before the division of cells. It helps in making sure that both the cells get an exact copy of the genetic material of their … WebbThe replication origin and the initiator protein DnaA are the main targets for regulation of chromosome replication in bacteria. ... Regulation of dnaA gene expression is also important for initiation. The principle of replication-coupled negative regulation of DnaA found in E. coli is conserved in eukaryotes as well as in bacteria.
