Chemically, the ribosomes are formed of...........

Explanation

### Step-by-Step Text Solution:

1. **Understanding Ribosomes**: Ribosomes are essential cell organelles that play a crucial role in protein synthesis. They are often referred to as the "protein factories" of the cell.

2. **Structure of Ribosomes**: Ribosomes are non-membrane bound organelles, meaning they do not have a surrounding membrane. They are typically described as having a pear-shaped or round structure.

3. **Chemical Composition**: The question specifically asks about the chemical composition of ribosomes. Ribosomes are primarily composed of two main components:
- **Ribonucleic Acid (RNA)**: This is the genetic material that plays a key role in coding, decoding, regulation, and expression of genes.
