Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
The capsid of a virus is made up of ____
A
Protein
B
DNA
C
RNA
D
Carbohydrates
E
Lipids
Explanation: 

Detailed explanation-1: -(A) Virus capsids are composed of viral protein subunits that form structural units.

Detailed explanation-2: -A capsid is a protein shell or a protein coat of a virus that encloses and protects the nucleic acid within. The capsid is made up of small subunits called capsomeres. These capsomeres are generally arranged in helical or polyhedral geometric forms to form the capsid.

Detailed explanation-3: -Viral Structure. In the simpler viruses the virion consists of a single molecule of nucleic acid surrounded by a protein coat, the capsid; the capsid and its enclosed nucleic acid together constitute the nucleocapsid.

Detailed explanation-4: -Capsid proteins, designated as VP1, VP2, VP3, and VP4, are important components of infectious virions. They protect viral genomes during entry and exit from the host cells and can also modulate the activity and specificity of viral replication complexes.
