Restriction enzymes were first discovered with the observation that

b. Bacteriophage DNA is destroyed in a host cell.

c. Foreign DNA is kept out of a cell.

d. Foreign DNA is restricted to the cytoplasm.

Post-translational control refers to:

In prokaryotes, control of gene expression usually occurs at the
