Viruses can't reproduce without a host; they can't reproduce on their own.
This necessitates the use of a host cell. When a virus enters a host cell, it releases its genetic content. As a result, viruses kidnap host cells and force them to make new viruses.
The lytic cycle and the lysogenic cycle are the two replication processes used by viruses. Some viruses use both mechanisms of reproduction, whereas others solely use the lytic cycle.
The virus binds to the host cell and injects its DNA during the lytic cycle.
The virus binds to the host cell and injects its DNA during the lytic cycle. a virus, on the other hand, can replicate and spread quickly if it finds a host.
