Show Answer
Answer:
Correct Answer: D
Solution:
The process in which a bacterial cell remains undestroyed and unaffected even in the presence of a phage is called Lysogen.
In lysogeny, temperate phages integrate their genomes into the bacterial chromosomes, known as lysogenization. The integrated phage genome is referred to as a prophage. The prophage is replicated together with the bacterial chromosome during cell division2. Temperate phage can remain in this state or switch to a lytic cycle via a process called induction.
This process allows the bacterium to continue living, while the phage DNA is passed on to each new generation of bacteria that results from cell division. The phage DNA can remain dormant in the bacterial chromosome until certain conditions trigger it to become active again. This is a survival strategy for the phage, allowing it to persist in the environment over long periods of time
