The bacteriophage incorporates in the viral genome in which phase?
Correct answer: A. Lysogenic cycle
- A. Lysogenic cycle
- B. Lytic cycle
- C. Both
- D. None
Explanation
Phages lave a lytic and lysogenic life cycle. In the lysogenic cycle, phages integrate their genetic material into the bacterial chromosome and replicate along with the host cells DNA without causing immediate cell lysis. In the lytic cycle, phages infect bacterial cells, hijack their machinery to replicate, and eventually cause the host cell to burst, releasing newly formed phages.

About Viruses
Viruses are acellular infectious particles made of genetic material enclosed by a protein capsid, sometimes with a lipid envelope. Their replication depends on a host cell and may follow lytic or lysogenic cycles, so viral structure and reproduction differ fundamentally from those of cellular organisms such as bacteria.
