The Genetic Code

The genetic code is a messenger RNA (mRNA) code. Each of the 64 triplet codons in the table is read 5' - 3'. The table is organized such that the first letter in the codon is read in the four blocks at the left, the second letter in the four columns across the top, and the third letter as a line in each block of four.
