Chapter 7 Protein Synthesis 1. Each tRNA molecule is designed to bind to a specific amino acid of the 20 amino acids. Aminoacyl tRNA synthetase is the enzyme which catalyze the coupling of amino acid to its tRNA molecule. DNA code is degenerate. Protein Synthesis Protein synthesis is catalyzed by ribosomes , which are large complexes of RNA and Protiens.
Large subunit catalyzes peptide bond formation.
