Q. Which of the following statement is false?
A) TMV has a double-stranded RNA molecule
B) Most plant viruses are RNA viruses
C) The bacteriophage has a double-stranded DNA molecule
D) Most animal viruses are DNA viruses
Explanation
Usually plant viruses contain RNA but some plant viruses contain DNA as genetic material. Most animal viruses contain DNA but there are some exceptions (with RNA as genetic material) also. In tobacco mosaic virus and tomato mosaic virus, genetic material is ss-RNA, while bacteriophage lambda and bacteriophage $T_{4}$ possess a linear ds-DNA molecule as genetic material.
