WebNot all components of the ribosome are made in the nucleolus. The 5S rRNA is transcribed by RNAPIII elsewhere. Ribosomal proteins are created first by transcription of an mRNA by RNAPII then translation of that mRNA in the cytosol. The newly-translated r-proteins are then imported back into the nucleus, into the nucleolus for ribosomal maturation.
