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.

WebNucleolus. The nucleolus (see Fig. 1-1) is a non–membrane-bound structure within the nucleus that forms around chromosomal loci of the ribosomal RNA (rRNA) genes known as nucleolar organizing regions (NORs).
