Question

Quizplus · Accepted Answer

Glycoproteins are the most common type of molecule found on the surface of animal viruses for interacting with host cell receptors. They have carbohydrate (sugar) molecules attached to protein molecules, which serve as the virus's key for unlocking receptors on the host cell surface. This interaction is critical for the virus to enter the host cell and replicate. Lipoproteins, phosphoproteins, and teichoic acids are not typically found on the surface of animal viruses.
