Question
Charging of tRNA is catalyzed by
Explanation
aminoacyl-tRNA synthetase is the accurate response regarding enzymatic activity or regulation described in this question. Enzymes are biological catalysts that accelerate reactions by lowering activation energy through specific substrate binding and transition state stabilization. In the context of Acid, Base, pH, aminoacyl-tRNA synthetase plays a specific catalytic or regulatory role determined by its active site configuration and mechanism of action. The other options (ribosome, RNA polymerase, and peptidyl transferase) are either different enzymes with distinct substrate specificities, act through different mechanisms, or are involved in separate metabolic pathways.
