Correct answers: C and D.

- C: mRNA includes a start codon (AUG) that signals the beginning of translation.
- D: After transcription, mRNA leaves the nucleus and travels to ribosomes in the cytoplasm for translation.

(Notes: A is wrong — mRNA is single‑stranded. B describes tRNA, not mRNA. E is wrong — mRNA exits the nucleus into the cytoplasm, not out of the cell membrane.)
