Which molecule is found only in the nucleus of eukaryotic cells, except during mitosis?

Explanation:
DNA stays housed in the nucleus for most of the cell’s life. Transcription happens inside the nucleus to produce RNA, which then travels to the cytoplasm where translation occurs. RNA isn’t confined to the nucleus because various RNA types function in the cytoplasm. During mitosis, the nuclear envelope breaks down and chromosomes (DNA) are organized in the cytoplasm, so DNA isn’t contained within an intact nucleus then. This makes DNA the molecule found only in the nucleus, except for the mitotic phase.
