What type of nucleic acid genome is present in Tobacco Mosaic Virus (TMV)?
Answer and explanation
Correct answer: D. Single-stranded RNA
- Step 1: TMV is a rod-shaped plant virus consisting of capsomeres arranged in a helical cylinder. Step 2. Its genetic material is a single positive-sense single-stranded RNA molecule coiled within the protein coat. Answer: Single-stranded RNA (ssRNA). Why not the others: Double-stranded DNA is in adenovirus and herpesviruses; double-stranded RNA is in rotavirus; single-stranded DNA is in parvoviruses.
