Abstract The genes coding for the two classes of ribosomal RNA molecules, 5S RNA and 18+28S RNA, have been localized in the Norway rat (Rattus norvegicus). The 18+28S RNA cistrons are found on three chromosomes, at secondary constrictions on the short arms of chromosomes 3 and 12 and at the telomere of the short arm of chromosome 11. These sites were confirmed using the silver staining technique for nucleolar organizer regions. Two sites were found for the 5S RNA genes; one is closely linked to the 18+28S gene site on chromosome 12. The second site is at or near the telomere of the long arm of chromosome 19.
