Question

Is there a cell wall in viruses?

Answer 1

Explanation:

1. In virology, viruses lack the cell walls that certain live things have, instead opting for a protective protein coat that covers the nucleic acid.
2. A capsid is a name for this type of coat.
3. An infectious agent that comprises a nucleic acid molecule encased in a protein sheath, is too small to be seen under a microscope, and can only replicate within the living cells of a host.
4. A capsid is a virus's protein shell that encases its genetic material.
5. It is built up of protomers, which are oligomeric (repeating) structural subunits formed of protein.
