Answer:
D. The virus uses the host cell to make new viral parts.
Explanation:
The virus is an organism that is incapable of replicating on its own without a living host cell. It needs to infect a living cell in order to reproduce. The infection cycle of a virus is the replication cycle. Viruses employ two major infection cycles: LYTIC or LYSOGENIC cycles.
In the lytic cycle, the virus initially attaches to specific receptor sites on the host cell membrane. It then penetrates the host cell and incorporate its genetic material into the host cell's genome. It employs the host's ability to express its genes and replicate to express its genes and make new proteins. At the end of the LYTIC cycle, new viral particles (virions) are produced and released by lysis of the host cell.
