Which of the following best describes lysogeny?
A
The active replication and lysis of bacterial cells by bacteriophages
B
The process by which bacteria form endospores under stress conditions
C
The integration of bacteriophage DNA into the bacterial chromosome as a prophage
D
The synthesis of peptidoglycan in bacterial cell walls
Verified step by step guidance1
Understand that lysogeny is a specific type of bacteriophage life cycle distinct from active replication and lysis.
Recall that in lysogeny, the bacteriophage DNA integrates into the bacterial chromosome rather than immediately causing cell destruction.
Recognize that this integrated viral DNA is called a prophage and can remain dormant within the host genome.
Differentiate lysogeny from other bacterial processes such as endospore formation and peptidoglycan synthesis, which are unrelated to bacteriophage infection.
Conclude that lysogeny is best described as the integration of bacteriophage DNA into the bacterial chromosome as a prophage.
