WebThe ribosome is thus ready to bind the second aminoacyl-tRNA at the A site, which will be joined to the initiator methionine by the first peptide bond (Figure 5). WebSep 17, 2024 · Most of what I've seen is that the ribosome moves. And that makes sense since more than one ribosome can be translating one mRNA at the same time. It would probably be messy if each ribosome moved the mRNA (the mRNA definitely doesn't move by itself) along while the other ribosomes are working on a different part. fly fishing ypsilanti miWebJan 17, 2016 · genetic material into functional proteins.
