Member of the American Chemical Society (ACS). Nucleolus is where ribosomes are assembled. The nucleolus is also in charge of transcribing and modifying rRNA. However the nucleolus is not an organelle but a space in the nucleus which is actively producing ribosome units.he nucleolus is also in charge of transcribing and modifying rRNA.

When are ribosomes used in the process of protein synthesis? When the cell needs to make a protein, mRNA is created in the nucleus. The mRNA is then sent out of the nucleus and to the ribosomes. When it is time to make the protein, the two subunits come together and combine with the mRNA.
