### Step 1: Identify Key Concepts
In molecular biology, snRNPs (small nuclear ribonucleoproteins) are essential components of the splicing machinery in eukaryotic cells. They are involved in the processing of pre-mRNA into mature mRNA.

### Step 2: Analyze Each Option
1. **PML Bodies:** These serve as sites for various nuclear functions, including the regulation of apoptosis and transcription. They do not specifically play a role in snRNPs processing or storage.
2. **Polycomb Bodies:** These are involved in gene silencing and chromatin remodeling and do not have a direct role in the processing or storage of snRNPs.
3. **Cajal Bodies:** These are multifunctional nuclear structures that are specifically involved in the assembly and maturation of snRNPs and small nucleolar ribonucleoproteins (snoRNPs).

### Step 3: Conclusion
Based on the analysis, Cajal bodies are indeed associated with the processing and storage of snRNPs.

### Final Answer
**Cajal Bodies** play a role in the processing and storage of snRNPs.
