There are two classes of release factors for translation termination. Choose correct statements
A. Class I release factors recognize the stop codons and trigger hydrolysis of the peptide chain from the tRNA in the P-site.
B. Prokaryotes have two class I release factors called RF1 and RF2. RF1 recognizes the stop codon UGA, UAA and RF2 recognizes the stop codon UAG and UAA.
C. In eukaryotic cells, there is a single class I release factor called eRF1 that recognizes all three stop codons.
D. Class II release factors stimulate the dissociation of the ribosome after release of the polypeptide chain.
