Eukaryotic ribosomal subunits are made in the _____, but they are assembled in the _____.

Explanation:
Ribosome production in eukaryotes starts with rRNA transcription and initial assembly in the nucleolus, the specialized region within the nucleus. The ribosomal proteins are made in the cytosol and then imported into the nucleus to join with the rRNA in the nucleolus to form pre-ribosomal subunits. After this partial assembly, the subunits are exported to the cytosol where they complete their maturation into the functional small and large subunits. That makes the correct pairing: made in the nucleolus, but assembled in the cytosol.
