Which of the following is the actual event that translates the language of nucleic acids (the sequence of bases, A, T (U), C, and G) to the language of proteins (determining which amino acid will be added to the polypeptide)?
a. binding of charged tRNA to the ribosome A site
b. catalysis of a new peptide bond from the growing polypeptide to the next amino acid
c. release of the finished polypeptide at the stop codon
d. attachment of the appropriate amino acid to the tRNA by aminoacyl tRNA synthetase
e. establishing the correct reading frame by the ribosome
