WebThis structure, along with several other structures with inhibitors bound, provide strong evidence that the ribosome is a ribozyme. Enzymes typically use amino acids to catalyze chemical reactions, but the ribosome appears to use an adenine RNA nucleotide to perform its synthetic task. 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.
