In lysogenic cycle the process of spearation of phage DNA from the hosts chromosome and initiation of lytic cycle is called______________?
Correct answer: C. Induction
- A. Lysis
- B. Lysogeny
- C. Induction
- D. Adsorption
Explanation
Induction is the excision of prophage DNA from the bacterial chromosome followed by entry into the lytic cycle, often after environmental stress. Lysis is the later rupture of the host cell, so students may choose it by focusing on the final outcome rather than the initiating process.

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.
