Many animal viruses exhibit icosahedral symmetry. How many triangular faces make up the capsid of a virus with this specific geometric arrangement?
Q1. Many animal viruses exhibit icosahedral symmetry. How many triangular faces make up the capsid of a virus with this specific geometric arrangement?
Answer: 20 faces
Explanation: Icosahedral symmetry is defined by 20 triangular faces; 12 refers to the number of vertices, not the faces.
