This region is characterized by a high concentration of transcription and processing factors. This region appears as a dense cluster under electron microscopy and serves as the storage and processing site for ribosomal DNA.
Nucleolus Structure Metabolic State Sensor: How rDNA Organization Tracks Cellular Energy
The Fibrillar Center: The rDNA Hub Located at the heart of the nucleolus structure is the fibrillar center (FC). The DFC is where the sequential processing steps occur, transforming the long precursor RNA into the mature 18S, 5.
8S, and 28S rRNA molecules. The nucleolus stands as a prominent subnuclear organelle, orchestrating the complex process of ribosome biogenesis.
Nucleolus Structure Metabolic State Sensor: The Fibrillar Center at the Core
Essentially, the fibrillar center acts as the genomic template factory, providing the raw genetic material necessary for the entire ribosome assembly line. Within the GC, the processed rRNA subunits combine with ribosomal proteins imported from the cytoplasm to form the small and large ribosomal subunits.
