C. The bacteriophage has a double-stranded DNA molecule.
D. Most animal viruses are DNA viruses.
Correct Answer :
A. TMV has a double-stranded RNA molecule.
Tobacco mosaic virus (TMV) is a single stranded RNA virus that infects a wide range of plants, especially tobacco and other members of the family solanacea. The infection causes characteristic patterns, such as mosaic-like mottling and discolouration on the leaves (hence the name). TMV was the first virus to be discovered.
