Molecular cloning generally uses DNA sequences from two different organisms: the species that is the source of the DNA to be cloned, and the species that will serve as the living host for replication of the recombinant DNA.
Molekulsko kloniranje je sklop eksperimentalnih metod v molekularni biologiji, ki jih uporabljamo za formiranje rekombinantnih molekul DNK in za usmerjanje njihovega podvojevanja (replikacije) v gostiteljskih organizmih.
