After transcription, mature mRNA is transported to the cytoplasm. Which option correctly states this process?

Explanation:
After transcription in the nucleus, the RNA is processed to become mature mRNA, then packaged with proteins to form an mRNP and exported through the nuclear pore into the cytoplasm. Translation happens there, so the mature message must leave the nucleus to be used. If it stayed in the nucleus, translation wouldn’t occur; if it were degraded right away, no protein could be made; and binding to DNA would imply a transcriptional role, not translation. Thus, the correct statement is that mRNA leaves the nucleus for the cytoplasm.
