Which of the following statements correctly describes how the host cell membrane is changed by viral replication?
Correct answer: D. Viral proteins are acquired
- A. Pores develop
- B. Glycocalyx layer is formed
- C. Membrane is resynthesized
- D. Viral proteins are acquired
Explanation
During attachment and penetration, the virus attaches itself to a host cell and injects its genetic material into it. During uncoating, replication, and assembly, the viral DNA or RNA incorporates itself into the host cell's genetic material and induces it to replicate the viral genome. So, option D is correct.

About Viruses
Viruses are acellular infectious particles made of genetic material enclosed by a protein capsid, sometimes with a lipid envelope. Their replication depends on a host cell and may follow lytic or lysogenic cycles, so viral structure and reproduction differ fundamentally from those of cellular organisms such as bacteria.
