WebRibosomes comprise of two subunits that are suitably composed and function as one to translate the mRNA into a polypeptide chain amid protein synthesis. Due to the fact that they are made from two subunits of differing size, they are a little longer in the hinge than in diameter. They vary in size between prokaryotic cells and eukaryotic cells. WebWithin the ribosome, the rRNA molecules direct the catalytic steps of protein synthesis — the stitching together of amino acids to make a protein molecule. In fact, rRNA is sometimes …

"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.
