The nucleolus is a compact structure present in the nucleus of fungal cells and all other eukaryotic cells. The nucleolus is not enclosed by a membrane. Nucleolar organizer present in the nucleolus contains the instructions for the synthesis of ribosomal RNAs.
Ribosomal proteins are synthesized in the cytoplasm. The ribosomal proteins are transported from the cytoplasm into the nucleolus. Assembly of ribosomal proteins and ribosomal RNAs to make ribosomal subunits occur inside the nucleolus which then enters cytoplasm to carry out protein synthesis.
