Viroids differ from viruses in having:
A
DNA molecules without protein coat
B
RNA molecules with protein coat
C
RNA molecules without protein coat
D
DNA molecules without protein coat
Answer
RNA molecules without protein coat
Explanation
Solution
Viroids differ from viruses in having RNA molecules without protein coat.
A virus is an infectious microorganism that comprises a segment of nucleic acid surrounded by a protein coat. On the basis of Genetic material, the virus is of two types, either DNA containing or RNA containing. Whereas viroid is infectious, highly structured small circular ribonucleic acids (RNAs) but does not contain protein as an outer covering.
Therefore, the correct option is option (C) RNA molecules without protein coat.
