Origin of replication
Discrete positions on a chromosome or vector DNA where replications are initiated. Vectors must have at least one origin of replication sequence for their replication in host cells.

The F-plasmid (also called F-factor) is an episome (a plasmid that can integrate itself into the bacterial chromosome by genetic recombination) of about 100 kb (kilo base pairs) length. It carries its own origin of replication, called oriV.
A first-generation episomal vector based on the latent origin of replication oriP and its transactivator EBNA-1 from EBV was used to establish and maintain up to 350 kb of circular DNA in human cells.
Cloning vectors minimally contain an origin of replication, selectable marker gene (e.g., ampicillin resistance gene), and multiple cloning site containing unique restriction enzyme sites; other useful features may also be present.
YAC, Yeast Artificial Chromosome A cloning vector based on a the essential components of a yeast chromosome. It provides two telomeres, two selectable markers and an origin of replication.
Replicon A segment of DNA that carries its own origin of replication and can replicate autonomously; bacterial plasmids are replicons.
Once the polymerases have opened the molecule, an area known as the replication bubble forms (always initiated at a certain set of nucleotides, the origin of replication).
