Kubva pamharadzano yakapiwa, bvisa dhayamita ye eukaryotic ribosomes.
Context:Prokaryotic ribosomes inenge 20 nm (200 Å) mu dhayamita uye inoumbwa ne65% rRNA uye 35% ribosomal protein. Eukaryotic ribosomes iri pakati pe25 ne30 nm (250<unk>300 Å) mu diameter ine rRNA-to-protein ratio iri pedyo ne1. Basa re crystallographic rakaratidza kuti hapana mapuroteni eribosomal ari pedyo nenzvimbo inoitwa polypeptide synthesis. Izvi zvinoratidza kuti mapuroteni ari muma ribosomes haabatanidzwi zvakananga mukuumbwa kwe peptide bond, asi kuti mapuroteni aya anoita sechinhu chinogona kuwedzera kukwanisa kwe rRNA kugadzira mapuroteni (Ona: Ribozyme).
