In icosahedral virus the capsomeres are arranged in _ triangles.
Correct answer: B. 20
- A. 1
- B. 20
- C. 3
- D. 4
Explanation
In icosahedral viruses, the capsomeres are arranged in equilateral triangles. An icosahedron is a geometric shape with 20 equilateral triangle faces, and the capsomeres, which are protein subunits that make up the viral capsid, are arranged in a way that conforms to the structure of the icosahedron. The equilateral triangles are a key feature of the icosahedral symmetry observed in many viruses.

About Viruses
Viruses are acellular infectious particles made of genetic material enclosed by a protein capsid, sometimes with a lipid envelope. Their replication depends on a host cell and may follow lytic or lysogenic cycles, so viral structure and reproduction differ fundamentally from those of cellular organisms such as bacteria.
