23 Which of the following statements is correct regarding translation termination in eukaryotes?
(A) The structure and amino acid sequence of the Class I eukaryotic release factors (eRFs) are similar with those of the Class I release factors in prokaryotes.
(B) eRF1 induces release of the nascent polypeptide from the peptidy1-transferase center.
(C) Rlil is an ATP-binding protein and brings eRF 1 to the ribosome.
(D) eRF3 is a GTP-binding protein and catalyzes release of eRF1 from the A-site.
(E) Neither eRF1 nor eRF3 participates in separation of the large and small ribosomal subunits after release of the nascent polypeptide.
