Question

Which is true about the lytic and lysogenic cycles of viruses? (1 point)

O The lysogenic cycle involves newly replicated virus bursting from the cell.

O The viral genome incorporates into the host genome during the lysogenic cycle.

The lytic cycle involves the merging together of the viral and host genomes.

The viral genome is injected into the cell only during the lytic cycle.

Answer 1

The viral genome incorporates into the host genome during the lysogenic cycle.

Explanation: In the lysogenic cycle the viral genome integrates into the host chromosome (as a prophage) and replicates with it. In the lytic cycle the virus replicates actively and causes host-cell lysis.
