In which of the following life cycles does a bacteriophage integrate itself into the host genome?

In good growth conditions the bacteriophage is more likely to enter into which life cycle?

Activation of which of the following genes leads to entrance into the lysogenic cycle?

The N protein is an anti-terminator. What does this mean?

Describe the difference between the bacteriophage lytic cycle and lysogenic cycle.

Describe the lytic and lysogenic life cycles of λ bacteriophage. What roles do λ repressor and Cro protein play in controlling transcription from P_R and P_RM, and how are these roles linked to lysis and lysogeny?
