What is there in the hereditary material of the virus of the mentioned disease?
Think it through first, then pick an option.

- c RNA
- d DNA
Answer and explanation
Correct answer: c RNA
The mosaic disease virus, TMV, has RNA as its hereditary material.
Why the other options are wrong
- a Centromere: The centromere is a part of the chromosome, not the hereditary material of the virus.
- b Locus: Locus is the position of a gene, not a hereditary material.
- d DNA: TMV has no DNA. The right answer is RNA.
