Answer: C. Cannot reproduce on its own
Step-by-step explanation:
Unlike Bacteria, Virus do not have the internal machinery to replicate. When a Virus infects a host, it invades the cells and introduces its genetic content to the host's cells nucleus, the host's cells begin to replicate the virus's genetic content. That's how a virus replicates.
- Virus infects host cell
- Viral DNA invades the host's cells nucleus
- Viral DNA replicates on the cell's nucleus
- Ribosomes produce the proteins coded by Viral RNA
- Viruses form from the proteins produced and exit the cell
