When a Bacterial Cell with a Chromosome-Borne F Factor Conjugates

Multiple Choice

When a bacterial cell with a chromosome-borne F factor conjugates with another bacterium, how is the transmitted donor DNA incorporated into the recipient's genome?

A) It is substituted for the equivalent portion of the recipient's chromosome by the process of crossing over.
B) It circularizes and becomes one of the recipient cell's plasmids.
C) Any genes on the donor DNA of which the recipient does not have are added to the recipient chromosome; the remainder of the donor DNA is degraded.
D) The donor and recipient DNA are both chopped into segments by restriction enzymes, and a new, composite chromosome is assembled from the fragments.
