Translation in eukaryotes occurs

Options

A. In the nucleus
B. On the ribosomes
C. In the nucleolus
D. In the Golgi complex

Answer

### Step-by-Step Solution

1. **Understanding Translation**:
- Translation is the biological process where ribosomes synthesize proteins based on the sequence of messenger RNA (mRNA). This process is crucial for protein production in cells.

2. **Location of Translation in Eukaryotes**:
- In eukaryotic cells, translation occurs primarily in the cytoplasm. This is where ribosomes are located, which are the cellular machinery responsible for protein synthesis.

3. **Role of Ribosomes**:
- Ribosomes can either be free-floating in the cytoplasm or attached to the endoplasmic reticulum (ER), forming what is known as rough ER. Both locations are involved in the translation process.

4. **Comparison with Other Options**:
- **Option A (in the nucleus)**: Translation does not occur in the nucleus; instead, the nucleus is where transcription (the process of converting DNA to RNA) takes place.
- **Option C (in the nucleus)**: This is incorrect for the same reason as Option A.
- **Option D (in the Golgi complex)**: The Golgi apparatus is involved in modifying, sorting, and packaging proteins, but it is not the site of translation.

5. **Conclusion**:
- Based on the understanding of where translation occurs in eukaryotic cells, the correct answer is **Option B: on the ribosomes**.

### Final Answer
The correct answer is **Option B: on the ribosomes**.
