3. If a bacterial colony is grown in a medium rich in the amino acid lysine, cell division proceeds rapidly and the colony grows steadily. If the lysine concentration drops, cell division slows; if the lysine concentration is restored, cell division resumes. Lysine is thus a(n)
a. fertilization signal.
b. ori site.
c. reproductive signal.
d. oncogene.
e. fission activator.

4. Which of the following would most likely result from a mutation in the ori gene of a bacterial cell?
a. The cell would not be able to detect whether conditions were favorable for replication.
b. The initiation of DNA replication would be hindered.
c. DNA replication would be prolonged abnormally.
d. The cell would not be able to segregate DNA molecules.
