Answer: The correct codon on the mRNA molecule is GUC.
tRNA ( transfer RNA) molecule contains a sequence of three bases in the anticodon loop, which are complementary to the mRNA ( messenger RNA) codon.
mRNA codon codes for a particular amino acid like GUC in this case codes for Valine, which is carried by the tRNA molecule in its amino acid attachment site.
When anticodon matches with the codon in the mRNA, amino acids are assembled in a particular order, which results in the synthesis of protein.
Thus, the codon for the anticodon CAG is GUC.
