摘要
The nucleolus is the site of ribosomal RNA synthesis, processing and ribosome maturation. Various small ribonucleoproteins also undergo maturation in the nucleolus, involving RNA modification and RNA-protein assembly. Such steps and other activities of small ribonucleoproteins also take place in Cajal (coiled) bodies. Events of ribosome biogenesis are found solely-in the nucleolus, which is the final destination of small nucleolar RNAs after their traffic through Cajal bodies. However, nucleoli are just a stopping point in the intricate cellular traffic for small nuclear RNAs and other ribonucleoproteins.
