tRNA is an important component of the protein-synthesizing system that functions as an adapter. The interaction between a tRNA and its corresponding amino acid requires their mutual recognition and subsequent attachment, which is catalyzed by:

• A. Aminoacyl-tRNA synthetase
• B. Aminoacyl-mRNA synthetase
• C. Peptidyl transferase
• D. RNA polymerase
• E. Aminoacyl-tRNA transferase
