Inside the nucleus in cells is another organelle called the nucleolus

Answer 1

The nucleolus is a distinct substructure located within the nucleus of a cell. It does not have a membrane surrounding it and is composed of protein and RNA. The primary function of the nucleolus is to produce and assemble ribosomes, which are responsible for protein synthesis within the cell. It acts as a site where ribosomal RNA (rRNA) genes are transcribed, processed, and combined with proteins to form ribosomal subunits. The nucleolus also plays a role in coordinating various cellular activities, including cell cycle progression and response to stress.
