88. Which statement for prokaryotic protein synthesis is FALSE?
(A) Protein synthesis begins at an AUG codon on the mRNA.
(B) The initial complex contains two main ribosomal subunits, the mRNA, GTP, and three initiation factors.
(C) The fMet-tRNAfMet binds to the P-site of the ribosome.
(D) After a chain elongation, the ribosome moves one codon, leaving a peptidyl-tRNA in the P-site and a new aminoacyl-tRNA entering the A site.
(E) When the ribosome encounters a stop codon, the chain is terminated in a process requiring GTP and three protein release factors.
