Question

Viroids differ from viruses in having :

• A. DNA molecules with protein coat
• B. DNA molecules without protein coat
• C. RNA molecules with protein coat
• D. RNA molecules without protein coat

Answer 1

The correct option is D RNA molecules without protein coat

Viroids are smaller than viruses, having free RNA as a genetic material and lack the protein coat that is found in viruses. Viruses, on the other hand, have either DNA or RNA as genetic material and a protein coat called capsid which protects the genetic material.
