The nucleolus: a paradigm for cell proliferation and aging
The nucleolus is the cellular site of ribosome biosynthesis. At this site, active ribosomal DNA (rDNA) genes are rapidly transcribed by RNA polymerase I (pol I) molecules. Recent advances in our understanding of the pol I transcription system have indicated that regulation of ribosomal RNA (rRNA) sy...
