The shape of the polio virus is:
Correct answer: A. Polyhedral shape
- A. Polyhedral shape
- B. Bad shape
- C. Tadpole shape
- D. Golf ball shape
Explanation
The polio virus has a polyhedral shape, which means it is roughly spherical with many flat sides or faces. The virus is made up of 60 identical protein units arranged in an icosahedral structure, which gives it its characteristic polyhedral shape. The outer surface of the virus is covered with a protective protein shell, which encases the viral genetic material inside.

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.
