Which of the following statements describes the lysogenic cycle of lambda (A) phage? After infection, the viral genes immediately turn the host cell into a lambda-producing factory, and the host cell then lyses. Most of the prophage genes are activated by the product of a particular prophage gene. The phage DNA is incorporated into the bacteria DNA The phage DNA is copied and exits the cell as a phage. The phage DNA get destructed by the host bacteria DNA

Viral Replication

The virus is acellular and considered non-living outside the host cell. The replication of the virus occurs only inside the living cells. Only a few genes are present in the smallest virus, whereas many genes are present in the largest virus. These genes encode specific viral proteins.
