the central and most important part of an object, movement, or group, forming the basis for its activity and growth.
The nucleolus is responsible for producing ribosomes, which are essential for protein synthesis in the cell. It also plays a role in storing and assembling ribosomal RNA (rRNA) and combining it with proteins to form ribosomal subunits.
The nucleolus is involved in ribosome production by synthesizing ribosomal RNA (rRNA) and assembling ribosomal subunits. It is also responsible for processing and modifying rRNA molecules before they combine with proteins to form ribosomes. Additionally, the nucleolus plays a role in cell cycle regulation and stress response mechanisms.
