Ribosomes are the macromolecular machines that are responsible for mRNA translation into proteins. The eukaryotic ribosome, also called the 80S ribosome, is made up of two subunits – the large 60S subunit (which contains the 25S [in plants] or 28S [in mammals], 5.8S, and 5S rRNA and 46 ribosomal proteins) and a small 40S subunit (which contains the 18S rRNA and 33 ribosomal proteins). The ribosomal proteins are encoded by ribosomal genes. WebJan 1, 2024 · Ribosome biogenesis is a multistep process, which involves rRNA and RP synthesis, and their assembly to make the mature ribosomes. Since the bacterial cell is a single noncompartmentalized membrane-bound biological chamber, all the steps of ribosome biogenesis are carried out in the cytosol.
