Part A Which of the following statements is NOT true of aminoacyl-tRNA synthetases? They activate the amino acid and covalently bond it to the mature tRNA. They attach the amino acid to the CCA at the 3'-end of the mature tRNA. They attach the amino acid to the elongating peptide and catalyze translocation. Each member of this protein family is dedicated to one particular amino acid. They are primarily responsible for the accuracy of mRNA translation Submit Request Answer Provide...
