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 the plasmid vector with the help of DNA Ligase enzyme and then introduced into the host cell. As when the plasmid replicates, this makes multiple copies of itself and thus foreign gene replicates and multiple copies are made. And when the host organism divides, its offspring receives the plasmid DNA contains the foreign gene.
