Question

Why do viruses have to infect host cells?

Answer 1

Viruses:

1. Viruses are infectious microbes that infect all living cells.
2. They are incapable of surviving independently and require a host to conduct their life processes.
3. They are parasitic in nature and require the host to provide energy and replicate.
4. Virus particles hijack the host cell and produce molecules required for viral reproduction.
5. When they are independent, they are considered non-living and reproduce only by infecting host cells.
