I gave my students this multiple choice question: Which activity is an important function of nucleases?

Only one answer is correct among these 4 choices:
- repairing the double strand of DNA
- concentrating RNA into a nucleolus
- maintaining homeostasis of nucleoplasm
- dissolving the nuclear membrane during mitosis

Could you tell me which one is correct?
