<h2>by ribosomes in the rough ER, and reach to the plasma membrane through the membrane of secretory vesicles.</h2>
Explanation:
The virus is made up of two types of macromolecules such as nucleic acid and proteins so-called as nucleoprotein. The viral infected cell produced virus particles because the virus captures the replication machinery of the host cell. In this process, the synthesis of glycoprotein takes place on the ribosomes that are present on the endoplasmic reticulum. The synthesized proteins reach the plasma membrane through the certain vesicles that are called as secretary vesicles.
