Which statement describes the difference between a lytic and lysogenic phage cycle? In a lytic cycle, new phage particles will be produced; in a lysogenic cycle, the phage DNA is passed to new cells but does not produce phage particles. In a lytic cycle, the host cell does not die; in a lysogenic cycle, the host is killed. In a lytic cycle, the phage DNA enters the host cell; in a lysogenic cycle, the phage DNA remains on the exterior of the host cell. In a lytic cycle, the phage DNA incorporates into the host genome; in a lysogenic cycle, the phage DNA does not incorporate into the host genome.

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.
