Phages and plasmids can be used to clone recombinant DNA.
A bacteriophage is a virus that infects and replicates within a bacterium. The term is derived from "bacteria" and the Greek: φαγεῖν, "to devour"
A plasmid is a small DNA molecule within a cell that is physically separated from a chromosomal DNA and can replicate independently. They are most commonly found in bacteria as small circular, double-stranded DNA molecules; however, plasmids are sometimes present in archaea and eukaryotic organisms.
