Detailed explanation-1: -Each time an amino acid is added to a growing polypeptide during protein synthesis, a tRNA anticodon pairs with its complementary codon on the mRNA molecule, ensuring that the appropriate amino acid is inserted into the polypeptide.

Detailed explanation-2: -To determine the overall anti-codon sequence that will match a strand of mRNA, simply retranscribe the RNA sequence; in other words, write out the complementary bases. Using the previously noted mRNA sequence, the tRNA anti-codon sequence is A-A-T-C-G-C-U-U-A-C-G-A.
