WebbA ribosome is a particle-like cell organelle made of RNA (ribonucleic acid) and ribosomal proteins that serve as the site for protein synthesis in the cell. Ribosomes consist of two major components: the small and large ribosomal subunits. WebbRibosomes ( / ˈraɪbəˌsoʊm, - boʊ -/) are macromolecular machines, found within all cells, that perform biological protein synthesis (mRNA translation). Ribosomes link amino acids together in the order specified by the codons of messenger RNA (mRNA) molecules to form polypeptide chains.
