How virus act?

Viruses act by invading host cells and hijacking the cell's machinery to replicate themselves. Once a virus attaches to a host cell, it injects its genetic material, which can be either DNA or RNA. This genetic material then directs the host cell to produce viral components, leading to new virus particles being assembled and released, often killing the host cell in the process. This cycle of infection and replication can spread the virus to other cells and hosts.
