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.
Nucleoplasm is also referred to as karyoplasm. 3. Nucleolus-can be called 'the nucleus of the nucleus'. As it is a part of the cell's organelle, it falls in to the category of sub-organelles.Nucleolus is responsible for the production of ribosomes-the protein-making devices of the cell.Ribosomes are cytoplasmic granules composed of RNA and protein. cell's endoplasmic reticulum (see chapter one of this topic) is attached to the nuclear envelope. 2. Nucleoplasm-liquid substance inside the nucleus which is similar to cell cytoplasm. Structural units of DNA and RNA (ribonucleic acid) and different enzymes are in nucleoplasm.
