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.
