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 ...

Ribosome biogenesis is a conserved, energy-intensive pathway that assembles ribosomal RNA (rRNA) and ribosomal proteins into functional small (40S) and large (60S) subunits. In eukaryotes, synthesis ...

Only recently has the ribosome—one of the oldest molecular machines in evolutionary terms—been recognized as an active regulator of gene expression at the level of protein biosynthesis. This is an ...

New research has uncovered shared patterns between ribosomal RNAs and genes linked to brain disorders, including autism, bipolar disorder, ADHD, and schizophrenia. Ribosomal RNA (rRNA) is a type of ...

In a study published in Nature Communications, researchers at Karolinska Institutet have mapped key steps in the assembly of ...

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 ...

We’re celebrating 180 years of Scientific American. Explore our legacy of discovery and look ahead to the future. In 1957, just four years after Francis Crick and other scientists solved the riddle of ...
