Question

Which has double-stranded RNA?

• A. Cauliflower mosaic virus
• B. TMV
• C. $\varphi \times$ 174
• D. Reovirus

Answer 1

Answer: (D)

Reoviruses contain double-stranded RNA (ds RNA) molecules as their genetic material. Tobacco Mosaic Virus (TMV) contains single-stranded DNA molecule as its genetic material. $\varphi$ x 174 contains single-stranded DNA molecule as its genetic material. Cauliflower Mosaic Virus (CMV) contains double-stranded DNA molecule as its genetic material.
