The correct Answer is:
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**.
