WebbIn eukaryotes, ribosomes consist of a small 40S and a large 60S subunit that together form the translation-competent 80S ribosome. The 40S subunit comprises the 18S ribosomal RNA (rRNA) as well as 33 ribosomal proteins (RPs), whereas the 60S subunit contains three rRNAs, the 25S/28S, 5.8S, and 5S rRNAs, as well as 46 RPs in yeast and 47 RPs in … WebbEukaryote cells include a variety of membrane-bound structures, together forming the endomembrane system. ...
