What is the protein coat that surrounds a virion’s nucleic acid called?
A
prion
B
capsid
C
envelope
D
viroid
Explanation: 

Detailed explanation-1: -Capsid is the protein coat that surrounds the nucleic acid in virus.

Detailed explanation-2: -The correct option is D capsomeres. A virus is a nucleoprotein which consists of the DNA or RNA as genetic material and protein coat called capsid. The protein coat (capsid) is made up of small subunits called capsomeres which protects the nucleic acid.

Detailed explanation-3: -A virus is made up of genetic material that is encased with a protective protein coat called the capsid. The capsid also helps the virus to infect host cells by binding to the host receptor proteins and releasing its genetic material.

Detailed explanation-4: -The protein coat which surrounds the genome (DNA or RNA molecules) of a virus is called the capsid. Capsid functions as a shell to protect the viral genome from degradative enzymes such as nucleases and also helps in the attachment of the virus to specific receptors exposed on the surface of their target host cells.
