Component Function Ribosomal DNA (rDNA) Template for ribosomal RNA transcription; located in NORs. During cell division, the nucleolus disappears as transcription halts, only to reassemble in the daughter cells once division is complete.
Nucleolus Facts: DNA Damage Response and Cellular Surveillance
Dynamic Assembly and Disassembly Unlike static organelles, the nucleolus undergoes constant assembly and disassembly in response to the cell cycle. The structure is highly organized into three main sub-regions: the fibrillar center, the dense fibrillar component, and the granular component.
snoRNAs Guide chemical modifications and cleavage of rRNA. Small nucleolar RNAs (snoRNAs) are essential guides for modifying ribosomal RNA, ensuring the final ribosomal subunits are correctly folded and functional.

Furthermore, the nucleolus has been implicated in the regulation of the tumor suppressor protein p53, linking its function directly to cancer biology. Ribosomal Proteins Structural and catalytic components of the final ribosome.
