Where do transcription and translation take place within the cell? What post-transcriptional modification aids in the movement of mRNA to the site of translation?
What will be an ideal response?
Transcription occurs in the nucleus. Translation occurs in the cytoplasm. The poly-A tail added to mRNA during post-transcriptional modification is a signal that allows mRNA to be exported from the nucleus to the cytoplasm.
