the exact mechanism by which viruses replicate vary, but the general process can be depicted as follows
In order for a virus to replicate it must infect a living cell.
the virus binds to the cell via a receptor-ligand interaction.
the virus, or just its genetic material, gain entry into the cytoplasm of the cell
The virus genetic material is then transcribed and translated into virus specific proteins, such as viron coat proteins.
new virus particles are then assembled
after the assembly of sufficient numbers of new viruses, the progeny viruses are released from the cell
