Description of a Plasmid and a Phagemid

Plasmid (type pUC) A plasmid is a small double-stranded DNA molecule (3 to 10 kb), circular, extrachromosomal, and capable of replicating (independently of the bacteria chromosome) in one bacterial cell and being transferred into another. Plasmids can be purified in large quantities because they multiply inside host bacteria.
