Replication origin

Replication origin

A unique dNA sequence of a replicon at which dNA replication is initiated and proceeds bidirectionally or unidirectionally. It contains the sites where the first separation of the complementary strands occurs, a primer rNA is synthesised, and the switch from primer rna to dNA synthesis takes place. (rieger et al., glossary of genetics: classical and molecular, 5th ed)

If the original question was a biology text book question or othrwise related to teaching, I believe ... you please specify as to how multiple initiation sites actually enhance the accuracy of replication? As far as I know, intitiation sites are realted to gene expression (i.e. the ...

How do they do it?

Briefly, what comes to DNA and replication (E. coli as an example model): there are several enzymes involved in the initiation. The enzyme complex recognizes the so-called origin of replication site by its typical nucleotide sequences (here several repeated sequences). ...
