Ribosomes are produced in

Options

A. Nucleolus
B. Cytoplam
C. Mitochondria
D. Golgi body

Answer

**Step-by-Step Solution:**

1. **Understanding Ribosomes**: Ribosomes are essential cellular structures responsible for protein synthesis. They can be found in both prokaryotic (70S) and eukaryotic (80S) cells, where they consist of two subunits.

2. **Identifying Ribosome Types**: In prokaryotic cells, ribosomes are referred to as 70S, which are made up of a 50S and a 30S subunit. In eukaryotic cells, ribosomes are termed 80S, composed of a 60S and a 40S subunit.

3. **Function of Ribosomes**: The primary function of ribosomes is to synthesize proteins, which are crucial for various cellular functions.

4. **Location of Ribosome Production**: The synthesis of ribosomes occurs in a specific part of the cell known as the nucleolus. The nucleolus is often referred to as the "ribosome factory" because it is where the components of ribosomes are assembled.

5. **Conclusion**: Therefore, the correct answer to the question "Ribosomes are produced in" is the **nucleolus**.
