Question

Which of the following statements describes the lysogenic cycle of lambda (λ) phage?A) After infection, the viral genes immediately turn the host cell into a lambda-producing factory, and the host cell then lyses.B) Most of the prophage genes are activated by the product of a particular prophage gene.C) The phage genome replicates along with the host genome.D) The phage DNA is copied and exits the cell as a phage.

Answer 1

Answer:

The correct answer is option C which is, "The phage genome replicates along with the host genome".

Explanation:

• The lysogenic cycle of the viruses are described as the replication of the virus inside the cell without lysing the cell as a result of replication.
• It is a host guest relationship.
• In this cycle, only viral genome replicate as part of host genome and it does not form phage inside the cell and not exit the host cell.
• While lytic cycle of virus replication leads to the lysis of cell and release of phages from the cell.
• Hence the correct answer is option C.
