Answer:
Step-by-step explanation:
In an icosahedral structure, the capsomeres are arranged in triangles.
An icosahedron is a polyhedron with 20 equilateral triangular faces. In the case of a viral capsid, which is the protein coat surrounding the genetic material of a virus, the capsomeres are the individual protein subunits that make up the capsid.
The capsomeres are arranged in a symmetrical pattern, forming equilateral triangles on the surface of the capsid. Each triangle consists of three capsomeres. This triangular arrangement allows for a stable and efficient packing of the capsomeres, ensuring the integrity of the capsid structure.
Therefore, the correct answer to the question is D) None of these. The capsomeres in an icosahedral structure are arranged in triangles, not in a specific quantity of 100, 200, or 1000.
