What is the duty of the release element in translation? A.It binds to the stop codon in the A website in place of a tRNA. B.It publication the ribosome from the ER to permit polypeptides into the cytosol. C.It publication the amino acid from the tRNA to enable the amino acid to type a peptide bond. D.It separates tRNA in the A website from the farming polypeptide.
