Name the three RNA polymerases found in eukaryotic cells and mention their functions.

Explanation

### Step-by-Step Solution:

1. **Introduction to RNA Polymerases in Eukaryotic Cells:**
Eukaryotic cells contain three main types of RNA polymerases, each responsible for synthesizing different types of RNA. These are RNA Polymerase I, RNA Polymerase II, and RNA Polymerase III.

2. **RNA Polymerase I:**
- **Function:**
- RNA Polymerase I is primarily responsible for synthesizing ribosomal RNA (rRNA), which is a crucial component of ribosomes.
