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.
