Answer:
Transcription.
Explanation:
During gene expression, information present in DNA gets transferred to RNA by the process of transcription. The synthesized RNA is then transported to the ribosomes (present in cytosol), where the process of translation.
Hence, due to the process of transcription, DNA remains in nucleus RNA molecule moves outside the nucleus and provides information for the protein synthesis, DNA remains in nucleus.
Thus, the correct answer is 'transcription.'
