explain boilogical role in in viral capsids in virus life cycle

Answer 1

Biological Role of Viral Capsid in Virus Life Cycle.

The viral capsid is a shell that is made up of organized protein sub-units known as the centromere. The centromeres have a close association with the viral nucleic acid and its majorly involved in configuration. During the life cycle of a virus, the viral capsid's primary role is to protect the nucleic acid from digestion by the host enzyme. The viral capsid also contains attachment sites that facilitate attachment of the virion to the host cells. Lastly, the viral capsid contains digestion proteins that facilitate entry into the host cell. If it is unsuccessful, it injects the viral nucleic acid into the host cell once an attachment has been established.
