Ribosomes are composed of two subunits, the small and large subunits, each containing specific rRNA molecules. The main types of rRNA include: Small Subunit rRNA: In prokaryotes, the small subunit ...
In eukaryotic cells, the nucleolus is the central site for ribosome biogenesis. It is composed of distinct subcompartments: fibrillar center (FC), dense fibrillar component (DFC), periphery of DFC ...
Reducing the metabolic burden of rRNA synthesis promotes healthy longevity in Caenorhabditis elegans
Ribosome biogenesis is initiated by RNA polymerase I (Pol I)-mediated synthesis of pre-ribosomal RNA (pre-rRNA). Pol I activity was previously linked to longevity, but the underlying mechanisms were ...
Liquid-liquid phase separation (LLPS) has been thought to be the biophysical principle governing the assembly of the multiphase structures of nucleoli, the site of ribosomal biogenesis. Condensates ...
