Match the Following

A. fidelity of codon recognition

1. involves two adjacent adenine residues in the 16S rRNA component located

within the A-site of the small subunit. These bases form hydrogen bonds with

the minor groove of each correct base pair formed between the anticodon and

the first two bases of the codon in the A-site

B. kinetic selectivity

2. 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. This, in turn, leads to a dramatic reduction in EF-Tu GTPase activity

C. Accommodation

3. When the charged tRNA is first introduced

into the A-site in a complex with EF-Tu-GTP, its 30 end is distant from the site of peptide-bond formation. To participate successfully in the peptidyl transferase reaction, the tRNA must rotate into the peptidyl transferase center of the large subunit in a process
