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.

Two trains of lengths 200m and 320m pass each other with constant speeds on parallel tracks in opposite directions. The drivers and guards are at extremities of the trains. The time gap between the drives passing each other and first driver-guard pair passing each other is 25 s. How much later will other driver-guard pair pass by?
