The vector, which is often a small, circular piece of dna that can exist outside the bacterial chromosome, is known as a plasmid.
Bacteria and certain other microscopic species contain plasmids, which are tiny circular DNA molecules. Physically distinct from chromosomal DNA, plasmids multiply on their own. They normally contain only a few genes, including some linked to antibiotic resistance, and they can spread from one cell to another.
Recombinant DNA techniques are used by scientists to splice the genes they want to research into a plasmid. The inserted gene is duplicated along with the plasmid when it duplicates itself. Molecular cloning, the process of creating DNA molecules and introducing them into a host cell, uses plasmid vectors as the means of delivering recombinant DNA into the host cell.
