Concept explainers

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.

Question

2. How would you be able to distinguish between a virus that is undergoing a lytic or lysogenic cycle? What makes each cycle unique?
