replica

...The genetic information of DNA is transmitted to the next generation of cells. If the DNA itself is a replicon, the DNA is easily stabilized. A replicon is a molecule that has a structure necessary for replication (a site that DNA replication enzymes recognize and start replicating). For example, bacterial circular DNA is a replicon.

A DNA replication unit that has a single replication origin, such as the chromosome of E. coli, and is accompanied by a group of factors that control the initiation of replication from that point, is called a replicon. The DNA of viruses and plasmids, as well as the DNA contained in mitochondria and chloroplasts, are also replicons, and each is subject to unique controls. …
