WebbNucleolus. 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). The nucleolus is the site of transcription and processing of rRNA and of assembly of preribosomal subunits.
