Question

When is the morphology of a virus said to be Icosahedral?

Answer 1

Icosahedral:

1. The icosahedral virus is a polyhedron with twenty faces it is made up of equilateral triangles fused symmetrically.
2. Icosahedral viruses increase the number of structural subunits or protomers in each face to expand their capsid size.
3. This is a place where the virus contains its genetic material for entering to host cell.
4. Icosahedral morphology is sometimes also referred to as cubic morphology
5. Examples: Cowpea chlorotic mottle virus (CCMV), an RNA virus, Poliovirus, Rhinovirus, and Adenovirus.
