Laga soo bilaabo marinka la bixiyay, soo saar dhexroorka eukaryotic ribosomes.
Context:Ribosomes prokaryotic waxay qiyaastii yihiin 20 nm (200 Å) dhexroor waxayna ka kooban yihiin 65% rRNA iyo 35% ribosomal proteins. Eukaryotic ribosomes waxay u dhexeysaa 25 iyo 30 nm (250<unk>300 Å) dhexroor leh rRNA-protein ratio oo ku dhow 1. Shaqada crystallographic waxay muujisay inaysan jirin borotiinno ribosomal ah oo ku dhow goobta falcelinta ee isku-darka polypeptide. Tani waxay soo jeedineysaa in qaybaha borotiinka ee ribosomes aysan si toos ah uga qaybqaadan kicinta sameynta isku xidhka peptide, laakiin ay tahay in borotiinnadani ay u dhaqmaan sida qalab kor u qaadi kara awoodda rRNA ee isku-darka borotiinka (Fiiri: Ribozyme).
