The protein coat of viruses is called the a. capsomere. Viruses replicate by binary fission.
Viruses are obligate intracellular parasites.
Prions are proteins that cause infectious diseases. A virus part that is involved in attachment and entry into cells is the a. capsomere. Aggregates of virions that sometimes are visible within a cell under a light microscope are called a. inclusion bodies. Viruses carried in the host for long periods of time without replication are called a. latent viruses. Proteins made by human cells that block viral replication are called a. interferons.
