Which of the following is a rod shape virus?
- A
Bacteriophage
- B
Herpes virus
- C
Hepatitis virus
- D
Tobacco mosaic virus
Tobacco mosaic virus (TMV) is a rod-shaped virus that infects plants, particularly tobacco and other solanaceous species. It has a helical structure, with a protein coat and a single-stranded RNA genome.
Bacteriophages are viruses that infect bacteria, and they come in various shapes, such as icosahedral, filamentous, or complex. While some bacteriophages may have a rod-like shape, it's not a defining characteristic.
Herpes viruses have an icosahedral capsid and are surrounded by an envelope, so they are not rod-shaped.
Hepatitis viruses are also enveloped viruses with an icosahedral or spherical shape, not rod-shaped.
