Question

Viroids differ from viruses in ______________.

• A. Satellite RNA packaged with viral genome
• B. Naked DNA molecules
• C. Naked RNA molecules only
• D. Naked DNA packaged with viral genome

Answer 1

The correct option is C Naked RNA molecules only

Viroids are the smallest infectious pathogens. They are composed of a short strand of circular, single stranded RNA without protein coat. Viroids cause infections in higher plants. Viruses can have either RNA or DNA molecules which is encapsulated in a protein coat. Viroids are smaller in size than viruses.

So, the correct answer is 'Naked RNA molecules only'.
