Vedclass · Answer

(D) For a foreign $DNA$ to multiply within a host cell,it must be integrated into the host's genome or be part of a vector (like a plasmid) that possesses an $ORI$ (Origin of Replication) sequence.If foreign $DNA$ is simply introduced into the cytoplasm or nucleoid without being linked to an $ORI$ sequence,the host cell's replication machinery will not recognize it as a template for replication.Therefore,foreign $DNA$ introduced into the cytoplasm or nucleoid cannot multiply on its own.Only $DNA$ linked to an $ORI$ sequence,such as when integrated into a plasmid,can replicate.
