Solution
The correct option is A Both assertion and reason are true and the reason is the correct explanation of the assertion In eukaryotes, transcription(DNA to RNA) and translation (RNA to protein) occur in the nucleus and cytoplasm respectively.

Thus, both assertion and reason are true and the reason is the correct explanation of the assertion.
