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 ...

Ribosomes are complexes of rRNA molecules and proteins, and they can be observed in electron micrographs of cells. Sometimes, ribosomes are visible as clusters, called polyribosomes. In eukaryotes ...

Improved RPL27A abundance facilitates the 5-FU-blocked rRNA processing (b), increases mature rRNA abundance, and promotes ribosome biogenesis and function (c), thus improving nucleolar integrity ...
