Question
When a foreign DNA is introduced into an organism, how is it maintained in the host and how is it transferred to the progeny of the organism?
✓

Answer

Foreign gene is usually ligated to a plasmid vector and introduced in the host. As plasmid replicates and makes multiple copies of itself, foreign gene also gets replicated and it's copies are also made. When the host organism divides, its progeny also receives the plasmid DNA containing the foreign gene.
