Plasmids are extrachromosomal genetic elements independent of main chromosome, typically small circular double-stranded DNA molecules capable of autonomous replication using their own origin of replication. They are nonessential for viability under standard conditions but confer selective advantages like antibiotic resistance, toxin production, or metabolic pathways. Copy number ranges from single to hundreds per cell. They transfer horizontally via conjugation if bearing tra genes. Laboratory cloning vectors derive from natural plasmids like ColE1 and F, engineered for replication and selection markers.

Plasmids are accessory genetic elements replicating independently of main chromosome through own origin of replication compatible with host initiation factors. Typically circular double-stranded DNA of few kilobases to over 100 kb, encoding antibiotic resistance, virulence, catabolic pathways or conjugation machinery, they are dispensable under non-selective conditions and may be lost without lethal effect. Found predominantly in bacteria, also in some archaea and eukaryotes. Classification by incompatibility groups and mobilization ability underlies biotechnology vectors derived from natural plasmids like pSC101 and pUC for cloning and expression.
