WebProkaryotic DNA Replication is the process by which a prokaryote duplicates its DNA into another copy that is passed on to daughter cells. Although it is often studied in the model organism E. coli, other bacteria show many similarities. Replication is bi-directional and originates at a single origin of replication (OriC). It consists of three steps: Initiation, … WebPlasmids are small double-stranded DNA molecules present in almost all bacterial cells (such as E. coli). The plasmid contains antibiotic-resistant genes, which can act as a selective marker in gene cloning. They are physically separated from bacterial DNA and can replicate independently of bacterial DNA.
