Before replication, the palindromic target GATC site is methylated by dam methylase on the N6 of A of each strand.

Replication generates hemimethylated DNA, in which one strand is methylated and one strand is unmethylated.

Thus, the replication event converts Dam target sites from fully methylated to hemimethylated condition.

There are two types of priming reaction in E. coli: The oriC system, named for the bacterial origin, basically involves the association of the DnaG primase with the protein

complex at the replication fork.
