Ribosomes consist of two major subunitsâthe small ribosomal subunit reads the mRNA, while the large subunit joins amino acids to form a polypeptide chain. Each subunit is composed of one or more ribosomal RNA (rRNA) molecules and a variety of proteins.
It consists of two subunits denoted 30S (small subunit) and 50S (large). When joined, the ribosome has a sedimentation coefficient of 70S as opposed to 80S due to tertiary structure. The subunits' shape and arrangement are illustrated below.
