The nucleolus

Curr Opin Cell Biol. 1994 Jun;6(3):354-9. doi: 10.1016/0955-0674(94)90026-4.


The transcriptionally active rRNA genes have the remarkable ability to organize and integrate the biochemical pathway of ribosome production into a structural framework, the nucleolus. The past year has seen numerous advances in our understanding of the relationships between nucleolar substructures, the site of ribosomal RNA (rRNA) gene transcription and the pathway of ribosome maturation. Progress has also been made both in the molecular identification of nucleolar constituents and in our understanding of the interactions between these components and their assembly into higher order structures.
