### Gene Expression Multiple Choice Question

**Question:**

During gene expression:

1. DNA exits the nucleus
2. Ribosomes enter the nucleus
3. RNA binds to ribosomes
4. Amino acids bind to DNA

**Explanation:**

For students studying gene expression, understanding the process is essential. This question tests your knowledge of the steps involved in gene expression. 

- **DNA exits the nucleus:** This is incorrect because DNA typically remains in the nucleus.
- **Ribosomes enter the nucleus:** Also incorrect as ribosomes are found in the cytoplasm.
- **RNA binds to ribosomes:** Correct. During translation, messenger RNA (mRNA) binds to ribosomes.
- **Amino acids bind to DNA:** This is incorrect. Amino acids do not bind directly to DNA; they are linked together to form proteins via ribosomes. 

Further study on the steps of transcription and translation will help clarify these concepts.
