Question

Viroids differ from viruses in having

D VINOD · Accepted Answer

## CORE INFORMATION
✓ **Answer**: A
## CONCEPT FRAMEWORK
**Primary Concept**: Differences between viroids and viruses
**Related Topics**: Nucleic acids, Genome structure
**Prerequisites**: Basic knowledge of virology, understanding of RNA and DNA
## SOLUTION PATHWAY
**Given Information**:
- Question asks for the key difference between viroids and viruses.
**Method & Steps**:
1. Recall the definition of viroids and viruses.
   Reasoning: Viroids are infectious agents composed only of a single-stranded circular RNA molecule. Viruses have a more complex structure with a protein coat and either DNA or RNA.
2. Compare the structure of viroids to the given options.
   Working: Viroids are known to have naked RNA molecules.
3. Identify the correct option.
   Result: Option A is the correct one.
## OPTION ANALYSIS
[A] ✓: Viroids are characterized by having naked RNA molecules without a protein coat.
[B] :x: Viroids do not have DNA; they have RNA.
[C] :x: Viroids do not have DNA or a viral genome. They consist only of their own RNA.
[D] :x: Viroids do not have satellite RNA and do not pack it with viral genome. They have only their own RNA.
## LEARNING AIDS
**Common Mistakes**:
1. Confusing viroids with viruses: Viroids are much simpler and do not have a protein coat or DNA.
2. Confusing RNA and DNA: Viroids are composed of RNA, not DNA.
**Quick Tips**:
1. Remember that 'viroid' sounds like 'RNA'.
2. Visualize viroids as simpler than viruses.
