What is the function of the release factor during translation in eukaryotes? (A) It binds to the stop codon in the A site in place of a tRNA. (B) It releases the amino acid from its tRNA to allow the amino acid to form a peptide bond. (C) It supplies a source of energy for termination of translation. (D) It releases the ribosome from the ER to allow polypeptides into the cytosol.
