Which of the following would NOT occur in a phage undergoing induction?
A) The transcription level of the int gene will increase, leading to production of the integrase.
B) Cleavage of the h repressor monomers inactivates the repressor protein.
C) There will be activation of the protease activity of RecA.
D) The transcription level of the xis gene will increase, leading to production of the enzyme excisionase.
E) UV damage to DNA can trigger the switch from lysogeny to the lytic cycle.

Question

During induction, the phage switches from the lysogenic to the lytic cycle, which involves excision of the prophage from the host genome. The int gene, responsible for integration, is not upregulated during induction; instead, the xis gene is upregulated to facilitate excision.
