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.
It is the nucleus that also contains the nucleolus structure to help synthesize the ribosomes in the cell. Nucleolus is also referred to as nucleole, which means, a cellular structure found in the nucleus of a eukaryotic cell. What is the Nucleolus of a Cell. Both animal and plant cells contains a nucleolus.As aforementioned, the nucleolus is a cellular structure present in the nucleus of a eukaryotic cell. In cell biology, the nucleolus is defined as a sub-organelle of the nucleus of a cell (which itself is an organelle).It is a round and typically, a small granular structured body which is composed of RNA and protein substances in the cell's nucleus.t is the nucleus that also contains the nucleolus structure to help synthesize the ribosomes in the cell.
