Question 1

The major function of the bacteriophage cro protein is to:

◦ prevent synthesis of the N protein.
◦ prevent synthesis of the Q protein.
◦ prevent synthesis of the cI protein.
◦ prevent synthesis of the cII protein.
◦ prevent synthesis of the xis protein.

Question 2

What effect would a cI^- mutation have on phage lambda infection?

◦ No effect, infection would proceed as normal to either lytic or lysogenic pathway
◦ Lytic pathway blocked, only lysogeny possible
◦ Lysogenic pathway blocked, only lytic pathway possible
◦ Complete abolishment of infection, neither lytic nor lysogenic pathway possible
◦ Higher levels of phage production than in wild-type phage
