Concept

Problem: If an aminoacyl-tRNA synthetase added the wrong amino acid to a tRNA, what would happen?A. The tRNA would associate with the wrong codon, and the wrong amino acid would be incorporate into the growing peptide.B. The ribosome would not be able to recognize the start codon, and translation would not be initiated.C. The tRNA could not bind to the ribosome, and no amino acid would be added to the growing peptide.D. The tRNA would carry the wrong amino acid, and it would be incorporated into the growing protein.E. The ribosome would not be able to recognize the stop codon, and translation would continue to occur when it should have been terminated.
