DNA, or the instructions for making proteins, is found within the nucleus of the cell; while protein synthesis machinery is found in the cytoplasm of the cell. <span>The nucleus is the site of transcription, production of messenger RNA (mRNA) and after being post-transcriptional modified mRNA is exported from the nucleus. Translation of mRNA occurs within the cytoplasm (proteins are synthesized).</span>
