One key function of nuclear pores is to

Options

A. aid in the production of new nuclei
B. allow cells to communicate with each other
C. form connections between different organelles
D. allow molecules like proteins to move in and out of the nucleus

Answer

To answer the question, "One key function of nuclear pores is to," we will analyze the options provided and determine the correct answer step by step.

### Step-by-Step Solution:

1. **Understanding Nuclear Pores**:
- Nuclear pores are large protein complexes that span the nuclear envelope, which is the double membrane surrounding the nucleus of a cell.
- They are crucial for the transport of molecules between the nucleus and the cytoplasm.

2. **Analyzing the Options**:
- **Option A: Aid in the production of new nuclei**:
- This option is incorrect. Nuclear pores do not play a direct role in the production of new nuclei.

- **Option B: Allow cells to communicate with each other**:
- This option is also incorrect. While communication between cells occurs, it is primarily through other structures like gap junctions, not nuclear pores.

- **Option C: Form connections between different organelles**:
- This option is incorrect as well. Nuclear pores specifically connect the nucleus to the cytoplasm, not between different organelles.

- **Option D: Allow molecules like proteins to move in and out of the nucleus**:
- This is the correct option. Nuclear pores facilitate the transport of proteins, RNA, and other molecules between the nucleus and the cytoplasm.

3. **Conclusion**:
- The key function of nuclear pores is to allow molecules like proteins to move in and out of the nucleus. Therefore, the correct answer is **Option D**.
