The correct answer is: assembles ribosomes.
Explanation:
The nucleolus is the largest structure in the nucleus of a cell body, granular, and round structure. The nucleolus is made up of components like RNA and proteins In the center of the nucleus of a cell.
This is associated with the synthesis of ribosomes and the formation of the rRNA or ribosomal RNA. The ribosomal RNA and proteins combine together to form subunits of the ribosomes that are move out of the nucleus to the cytoplasm in order to perform their function.
Thus, the correct answer is: assembles ribosomes.
