The main function of the nucleolus is to produce and assemble ribosomes, which are essential for protein synthesis in the cell. It is a dense, membrane-less structure located within the nucleus, where ribosomal RNA (rRNA) is transcribed, processed, and combined with ribosomal proteins to form the subunits of ribosomes. These subunits are then transported to the cytoplasm, where they play a critical role in translating messenger RNA (mRNA) into proteins. Additionally, the nucleolus is involved in regulating cellular stress responses and controlling the cell cycle.
