उत्तर

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