Prokaryotic DNA replication is the process by which a [[prokaryote]] duplicates its entire [[genome]] into another copy that is passed on to daughter cells.<ref>{{cite web|title=What is DNA Replication?|url=http://www.yourgenome.org/facts/what-is-dna-replication|website=yourgenome.org|publisher=Wellcome Genome Campus|accessdate=24 February 2017}}</ref> Although it is often studied in the [[model organism]] ''[[E. coli]]'', other [[bacteria]] show many similarities.<ref name=":0">{{Cite journal|last=Wolański|first=Marcin|last2=Donczew|first2=Rafał|last3=Zawilak-Pawlik|first3=Anna|last4=Zakrzewska-Czerwińska|first4=Jolanta|date=2014-01-01|year=2014|title=oriC-encoded instructions for the initiation of bacterial chromosome replication|url=https://www.ncbi.nlm.nih.gov/pubmed/25610430|journal=Frontiers in Microbiology|volume=5|pages=735|doi=10.3389/fmicb.2014.00735|pmc=4285127|pmid=25610430|via=}}</ref> Replication is bi-directional and originates at a single [[origin of replication]] (OriC).<ref>{{Cite journal|last=Bird|first=R.

'''[[DNA replication]] in [[prokaryote]]s''' is exemplified in ''[[E. coli]]''. It is bi-directional and originates at a single [[origin of replication]] (OriC).
