DnaG primase associates transiently with the replication complex, and typically synthesizes a 10-base primer. Primers start with the sequence pppAG positioned opposite the sequence 3’–GTC-5’ in the template.

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.
