"The human 80S ribosome is composed of a 40S and a 60S subunit. The chief function of the 40S subunit, which contains one strand of 18S ribosomal RNA (rRNA) and 33 distinct RPs, is to bind, unwind and scan mRNAs, whereas the 60S subunit is responsible for peptide bond formation and quality control of nascent peptides and is composed of three strands of rRNA (5S, 5.8S and 28S rRNA) and 47 distinct RPs," cited from https://ribosome.creative-biol....abs.com/ribosome-in-
