One mechanism that contributes to the fidelity of codon recognition involves the 16S rRNA other than initiation. Which of the following statements are correct in this phenomenon?
A. Codon recognition involves two adjacent uracil residues in the 16S rRNA component
B. The adjacent residues in the 16S rRNA do not discriminate between G:C or A:U base pairs and recognize either as correct
C. Even a single mismatch in the codon–anticodon base pairing alters the position of EF-Tu, reducing its ability to interact with the factor-binding center 16s rRNA, leads to a dramatic reduction in EF-Tu GTPase activity
D. Pyrophasphatic editing is key mechanism to ensure fidelity
