The nucleolus is the nuclear subdomain that assembles ribosomal subunits in eukaryotic cells. The nucleolar organiser regions of chromosomes, which contain the genes for preâribosomal ribonucleic acid (rRNA), serve as the foundation for nucleolar structure.
The nucleolus is contained within the cell nucleus. The nucleolus (/njuËËkliËÉlÉs/ or /ËnjuËkliËoÊlÉs/, plural nucleoli /njuËËkliËÉËlaÉª/ or /ËnjuËkliËoÊlaÉª/) is the largest structure in the nucleus of eukaryotic cells, where it primarily serves as the site of ribosome synthesis and assembly.
