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 a prominent sub-nuclear structure that is not bound by a membrane and resides within the nuclear matrix. Though known to exist since the eighteenth century, the primary function of the nucleolus was not discovered until the 1960s. It is now been determined that nucleoli manufacture the subunits that combine to form ribosomes, the cell's protein-producing factories.
