T.O. Diener (1971) discovered 'viroids' as the causative agent of potato spindle tuber disease. How do viroids structurally differ from conventional viruses?

Viroids consist of free, low-molecular-weight RNA that completely lacks a protein coat
Viroids consist of high-molecular-weight double-stranded DNA wrapped in capsomeres
Viroids consist exclusively of misfolded proteins devoid of any nucleic acid genome
Viroids consist of single-stranded RNA enclosed inside a thick chitinous cell wall

Correct answer · Option 1

Viroids consist of free, low-molecular-weight RNA that completely lacks a protein coat

Explanation

Viroids were found to be free RNA lacking a protein coat that is found in viruses; hence the name viroid. The RNA of the viroid was of low molecular weight.
