Question

Viroids have

• A. double stranded RNA enclosed by protein coat
• B. double stranded DNA enclosed by protein coat
• C. single stranded DNA not enclosed by protein coat
• D. single stranded RNA not enclosed by protein coat

Answer 1

The correct option is D single stranded RNA not enclosed by protein coat

Viroids are among the smallest infectious pathogens known, larger only than prions. Viroids consist solely of short strands of circular, single-stranded RNA without protein coats. They are mostly plant pathogens, some of which are of economic importance.
