Comments "The eukaryotic ribosome has a sedimentation coefficient of 80S and, with a minimal mass of ~3.3MD (yeast and plants), is roughly 40% larger than its bacterial counterpart (70S). The large 60S subunit consists of three rRNA (rRNA) molecules (25S, 5.8S, and 5S) and 46 proteins, whereas the small 40S subunit includes only one rRNA chain (18S) and harbors 33 proteins."
