Ribosomal RNA - Wikipedia
WEBRibosomal RNA is transcribed from ribosomal DNA (rDNA) and then bound to ribosomal proteins to form small and large ribosome subunits. rRNA is the physical and mechanical factor of the ribosome that forces transfer RNA (tRNA) and messenger RNA (mRNA) to process and translate the latter into proteins.

Ribosomal RNA (rRNA) | Definition & Function | Britannica
WEBJul 18, 2024 — Ribosomal RNA is a molecule in cells that forms part of the protein-synthesizing organelle known as a ribosome and that is exported to the cytoplasm to help translate the information in messenger RNA into protein.
Ribosomal RNA (rRNA): Definition & Function - Biology Dictionary
WEBOct 4, 2019 — Ribosomal ribonucleic acid (rRNA) is the RNA component of ribosomes, the molecular machines that catalyze protein synthesis. Ribosomal RNA constitute over sixty percent of the ribosome by weight and are crucial for all its functions – from binding to mRNA and recruiting tRNA to catalyzing the formation of a peptide bond between two …
Ribosome - Wikipedia
WEBRibosomes ( / ˈraɪbəzoʊm, - soʊm /) are macromolecular machines, found within all cells, that perform biological protein synthesis ( messenger RNA translation). Ribosomes link amino acids together in the order specified by the codons of messenger RNA molecules to form polypeptide chains.
