Thus, nucleolus is a sub-organelle, whereas nucleus is the main organelle within a cell. Nucleolus plays an indirect but crucial role in protein synthesis by assembling the ribosome subunits. (ii) Synthesis and storage of RNA: It produces 70-90% of cellular RNA in many cells. They are made and packaged in the nucleolus, a small dense region within the nucleus, by a process called ribosome biogenesis.
