WebThe seryl-tRNA anticodon (UCG) 5′-GCU-3′ base pairs with two serine codons, 5′-AGC-3′ and 5′-AGU-3′. Generally, Watson-Crick pairing occurs between AGC and GCU. However, in AGU and GCU pairing, hydrogen bonds are formed between G and U. Such abnormal pairing called ‘Wobble pairing’ is given in Table 7.5. WebApr 28, 2024 · Base pairing between the codon and anticodon brings specificity to the process of translation. On one end of the tRNA, an appropriate amino acid is attached to its 3’ hydroxyl group based on the anticodon and the ribosome catalyzes the formation of a peptide bond between this amino acid and the elongating polypeptide chain.
