Respuesta :
Viruses use the cell receptors to enter the cell.
Option D.
Explanation:
Viruses are the small intracellular pathogens which cannot reproduce on their own. A viral particle can make other virus particles only when it is inside the host. To gain entry inside the host, viral particles interact with the cell receptors of the host through which they are either endocytosed or inject their genetic material inside the host cell.
Once the viral genetic material RNA or DNA is inside the host it takes over the host replication machinery to replicate viral genome and to transcribe the viral proteins to produce more viral particles which rupture the cell and released to invade other cells.
