What is the shape of the TMV Virus?
Correct answer: A. Rod
- A. Rod
- B. Spherical
- C. Tadpole
- D. Helical
Explanation
The shape of TMV virus is rod-shaped or filamentous. TMV stands for Tobacco Mosaic Virus, and it is a type of virus that infects plants, particularly tobacco plants. The virus consists of a long, cylindrical structure that is made up of many copies of a single protein molecule that wrap around a single strand of RNA. The RNA contains the genetic information that the virus uses to replicate and produce more virus particles. The rod-shaped or filamentous shape of the virus is important for its ability to infect and move through plant tissues. The shape allows the virus to move efficiently through the narrow spaces between plant cells, and it also helps it to evade the plant's immune system.

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.
