Chapter 32, Problem 7P

Interpretation Introduction

Interpretation:

The mutation in the O_R2 gene affects the likelihood of bacteriophage lambda entering the lytic state. The reason for this statement should be determined.

Concept introduction:

The lytic cycle is the rupture of the host cell, resulting in the release of a number of viruses. Bacterial viruses undergo lytic cycle only and are termed as the virulent bacteriophages. These viruses are the cause of their host cells death. Another life cycle of bacteriophage includes a lysogenic cycle. In this cycle, the viral DNA remains in the inactivated state even after various reproduction cycles of the host bacterium. After a certain time only, the viral DNA is released from the host’s cell DNA and undergoes lytic cycle.
