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 about the key function of nuclear pores, we will follow these steps:

### 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 in eukaryotic cells.

2. **Function of Nuclear Pores**:
- The primary function of nuclear pores is to regulate the transport of molecules between the nucleus and the cytoplasm. This includes the movement of proteins, RNA, and other molecules.

3. **Transport Mechanism**:
- Nuclear pores act as channels that allow specific molecules to pass through. They facilitate the import of proteins into the nucleus and the export of RNA and ribosomal subunits out of the nucleus.

4. **Key Processes Involved**:
- In addition to transport, nuclear pores are involved in chromatin organization, gene expression regulation, and DNA repair processes. These functions highlight the importance of nuclear pores in maintaining cellular function and integrity.

5. **Conclusion**:
- Based on the above understanding, the correct answer to the question is that one key function of nuclear pores is to allow proteins and other molecules to move in and out of the nucleus.

### Final Answer:
The key function of nuclear pores is to allow proteins and other molecules to go inside and outside the nucleus.
