To determine the order of bases in the first column (UNA), second column (codon) and the third column Is the anticodon. Consider the complementary base pair, in DNA and in RNA To identify the amino acid, took at the bases in the MRNA codon, example AUG using the Genetic Code Table. Loo: for the first letter of the MRNA codon on the left side of the genstis code table (A), the second letter of the MRNA on the second letter column (U), and the third letter on the right-side column (G).
