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.

Ribosomes. 1  Ribosomes are the site for protein synthesis of the cell. 2  It is composed of two subunits, a small subunit and a large subunit. 3  The ribosomes subunits acts as an assembly line where the RNA from the nucleus is used to synthesize proteins from amino acids.rganelles like the nucleus and golgi apparatus are usually single while others like mitochondria, chloroplasts, peroxisomes and lysosomes are in large numbers about hundreds to thousands. The cellular organelles are suspended and surrounded in a gelatinous fluid cytosol that fills the cell.
