Question

Do viruses have a protein coat?

Answer 1

Virus:

1. A virus is an infectious submicroscopic creature that only reproduces inside live cells. All forms of life, including bacteria and archaea, as well as animals and plants, are susceptible to virus infection.
2. A capsid is a virus's protein shell that encases its genetic material. It is built up of protomers, which are oligomeric (repeating) structural subunits formed of protein.
3. Viruses contain capsids, which are protein covers that safeguard their genetic content.
4. The capsid is also wrapped by an envelope, which is a lipid bilayer coat.
5. Capsomeres are visible 3-dimensional morphological subunits that may or may not correlate to particular proteins.
6. Capsid proteins or viral coat proteins are the proteins that make up the capsid (VCP). The nucleocapsid is the combination of the capsid and the inner genome.
