Explanation:
Detailed explanation-1: -A virus is an infectious particle that reproduces by “commandeering” a host cell and using its machinery to make more viruses.
Detailed explanation-2: -Viruses are microscopic biological agents that invade living hosts and infect their bodies by reproducing within their cell tissue. Viruses are tiny infectious agents that rely on living cells to multiply.
Detailed explanation-3: -Replication (lysogenic cycle): When the host cell replicates, viral DNA is copied along with host cell DNA. Each new daughter cell is infected with the virus. Induction: When the infected cells are exposed to certain environmental conditions, viral DNA is activated and enters the lytic cycle.
