<P> The amino acid is coupled to the penultimate nucleotide at the 3 ' - end of the tRNA ( the A in the sequence CCA ) via an ester bond ( roll over in illustration ) . The formation of the ester bond conserves a considerable part of the energy from the activation reaction . This stored energy provides the majority of the energy needed for peptide bond formation during translation . </P>
