When the viral DNA becomes active in the lysogenic cycle, which life cycle does it enter? A. lytic
B. lysogenic
C. cell cycle
D. DNA replication

A.lytic

Explanation:

Lysogenic and lytic cycles are two cycles of viral reproduction. In the lysogenic cycle,  the viral DNA is incorporated into the host cell genome. Then, it can be passed on to the cell's daughter cells after it divides.

The other cycle of viral reproduction is called the lytic cycle. In the lytic cycle, the DNA is activated (transcribed). Viral particles can then assemble and replicate, and lyzing the host cell.
