Which of the following is true concerning a lysogenic viral replication cycle?

a. Lysogenic infections are similar to persistent infections in that virus is constantly produced.

b. During lysogeny, the viral genome integrates into the host DNA, becoming a physical part of the chromosome.

c. During lysogeny, the host DNA is degraded.

d. Once the lysogenic portion of the cycle has begun, virus is never produced again.

b. During lysogeny, the viral genome integrates into the host DNA, becoming a physical part of the chromosome.

Explanation:

Lysogenic viral replication cycle -

It is the one of the cycle of the viral reproduction.

It is also called as lysogenic cycle or Lysogeny.

In the Lysogeny, the integration of the bacteriophage nucleic acid lead to the formation of the circular replicon or into the bacterium's genome in the cytoplasm of the bacteria.

hence, the correct statemnet for the Lysogenic viral replication cycle is (b).
