In an animal cell, the processes of transcription and translation occur in

Options

A. nucleus only
B. cytoplasm only
C. nucleus and cytoplasm respectively
D. endoplasmic reticulum

Answer

To answer the question about where transcription and translation occur in an animal cell, we can break it down into clear steps:

### Step-by-Step Solution:

1. **Understanding Transcription**:
- Transcription is the process where the DNA sequence is copied into messenger RNA (mRNA).
- This process involves the enzyme RNA polymerase, which synthesizes mRNA from the DNA template.

2. **Location of Transcription**:
- In animal cells, transcription occurs in the **nucleus**.
- The nucleus contains the cell's genetic material (DNA), which is necessary for the transcription process.

3. **Understanding Translation**:
- Translation is the process where the mRNA is used as a template to synthesize proteins.
- This process occurs with the help of ribosomes, which read the mRNA sequence and assemble amino acids into a polypeptide chain.

4. **Location of Translation**:
- In animal cells, translation occurs in the **cytoplasm**.
- Ribosomes can be found either freely floating in the cytoplasm or attached to the rough endoplasmic reticulum (RER).

5. **Conclusion**:
- Therefore, in an animal cell, transcription occurs in the **nucleus**, and translation occurs in the **cytoplasm**.

### Final Answer:
Transcription occurs in the nucleus, and translation occurs in the cytoplasm.
