Which of the following statement is FALSE?
Options
- ATMV has a double stranded RNA molecule.
- BMost plant viruses are RNA viruses.
- CBacteriophage has a double stranded DNA molecule.
- DMost animal viruses are DNA viruses.
Correct answer
A. TMV has a double stranded RNA molecule.
Step-by-step solution
Tobacco mosaic virus (TMV) is a virus of the tobacco plant and infects a wide range of plants mainly members from the family Solanaceae. This virus has single stranded RNA as the genetic material. Bacteriophages are viruses that infect bacteria and their genetic material is double stranded DNA. Also, majority of the animal viruses are DNA viruses. Although, the viruses infecting plants are mainly RNA viruses.
