Prokaryotic ribosome structure

WebRibosomes in the cytoplasm of eukaryotic cells have a sedimentation coefficient of about 80 S (MW about 4.5 x 10 6) and are composed of 40 S and 60 S subunits. In prokaryotic cells, ribosomes are typically about 70 S (MW about 2.7 x 10 … WebRibosomes are molecular machines that synthesize proteins. Despite these similarities, prokaryotes and eukaryotes differ in a number of important ways. A prokaryote is a simple, single-celled organism that lacks a nucleus and membrane-bound organelles.
