A plasmid is a circular dsDNA molecule that is present in some bacteria. Plasmid DNA can be replicated and passed on to other cells through vertical genetic transfer via [binary_fission] or horizontal transfer via [conjugation].  During the later process, the donor cell transfers the plasmid to a recipient cell. The genetic information is passed through an appendage called the [sex_pilus].
