How does a virus duplicate
After gaining entry into the body, a virus makes physical contact with and crosses the plasma membrane of a target cell. Inside, it releases and replicates its genome while facilitating the manufacture of its proteins by host ribosomes. How this is carried out depends upon the type of viral nucleic acid.
