What type of virus is the smallpox virus?
Correct answer: A. DNA enveloped virus
- A. DNA enveloped virus
- B. RNA enveloped virus
- C. DNA virus
- D. RNA non-enveloped virus
Explanation
Like other OPXVs, VARV and MPXV produce large brick-shaped particles that are approximately 140-260 nm in diameter and 220-450 nm long, containing a linear DNA genome approximately 200 kb in length. The genome, enclosed within an enveloped capsid, is monopartite and encodes around 200 genes.

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.
