Viruses replicate by entering a host cell and utilizing the host's cellular machinery to produce more virus particles. This process is referred to as lysis. Once inside the host cell, the virus injects its genetic material, which hijacks the cell's processes to replicate its components, such as proteins and nucleic acids. Eventually, this results in the assembly of new viruses, which then exit the host cell, typically causing the cell to rupture (lyse) in the process. This lytic cycle is a key characteristic of many viruses, distinguishing their reproductive strategy from that of microorganisms like bacteria, which can replicate through methods such as fission or binary fission. In contrast, the replication process described here does not align with asexual reproduction as understood in cellular organisms, since viruses are not considered living entities outside a host and do not replicate independently.
