Ribosome is mainly formed of

Options

A. Enzymes
B. DNA
C. RNA
D. None of the above

Answer

### Step-by-Step Solution:

1. **Understanding Ribosomes**: Ribosomes are essential cellular structures known as the "protein factories" of the cell because they are the primary site for protein synthesis.

2. **Composition of Ribosomes**: Ribosomes are mainly composed of two components:
- Ribonucleic Acid (RNA)
- Proteins

3. **Structure of Ribosomes**: Ribosomes consist of two subunits:
- A larger subunit
- A smaller subunit

4. **Function of Subunits**:
- The large subunit is responsible for joining amino acids together to form polypeptide chains.
- The small subunit reads the messenger RNA (mRNA) to ensure the correct sequence of amino acids is assembled.

5. **Conclusion**: Since ribosomes are primarily made up of ribosomal RNA (rRNA) and proteins, the correct answer to the question "Ribosome is mainly formed of" is **RNA**.

### Final Answer:
Ribosome is mainly formed of **RNA**.
