Explanation:
Detailed explanation-1: -Answer: The matching mRNA codon for AUG anticodon is-UAC.
Detailed explanation-2: -Methionine: the mRNA codon is AUG, and the tRNA anticodon is UAC.
Detailed explanation-3: -Therefore the anticodon for UUC is AAG, for AUC it is UAG, for CCG it is GGC, and for CGU it is GCA.
Detailed explanation-4: -A tRNA with the complementary anticodon is attracted to the ribosome and binds to this codon. The tRNA carries the next amino acid in the polypeptide chain. The first tRNA transfers its amino acid to the amino acid on the newly arrived tRNA, and a chemical bond is made between the two amino acids.
Detailed explanation-5: -The tRNA anticodon 3-UAC-5 will pair with the mRNA codon.
