Ribosomal RNA (rRNA) is found in ribosomes and in the nucleolus where it is manufactured. messenger RNA (mRNA) can be found in the nucleus when it is translating DNA to mRNA in translation. It can also be found in the cytoplasm or attached to ribosomes that are transcribing the mRNA to synthesise polypeptides/protiens.
