Preferred Label : cell nucleolus;
MeSH definition : Within most types of eukaryotic CELL NUCLEUS, a distinct region, not delimited by
a membrane, in which some species of rRNA (RNA, RIBOSOMAL) are synthesized and assembled
into ribonucleoprotein subunits of ribosomes. In the nucleolus rRNA is transcribed
from a nucleolar organizer, i.e., a group of tandemly repeated chromosomal genes which
encode rRNA and which are transcribed by RNA polymerase I. (Singleton & Sainsbury,
Dictionary of Microbiology & Molecular Biology, 2d ed);
MeSH synonym : nucleolus, cell; nucleoli, cell; cell nucleoli; plasmosome; plasmosomes;
Wikipedia automatic translation : Nucleolus;
MeSH annotation : A 11 qualif except /cytol; /genet permitted;
