WebJan 3, 2024 · (1) The mRNA contains a sequence 237 that mediates its binding to the small ribosomal subunit. This sequence is located near the 5’ end of the mRNA. (2) the mRNA-small ribosome subunit complex now interacts with and binds to a complex containing an initiator (start) amino acid:tRNA. WebMar 19, 2024 · Ribosomes from bacteria and archaea consist of a large (50S) and a small (30S) subunit, which together constitute an approximately 2.5 megadalton (MDa) 70S ribosome. The eukaryotic counterparts are the 60S and 40S subunits and the 80S ribosome, which range in size from 3.5 MDa in lower eukaryotes to 4.0 MDa in higher eukaryotes.
