>>7180854When DNA is transcribed into RNA and then translated into Amino Acids the code involves three nucleotides of either AUGC. The picture shown depends on the first nucleotide at the center and radiates outward till you have 3 letters. Then the three letter word like Arg corresponds to an amino acid (Arginine) formed by the codon . The structures of all 20 amino acids are shown surrounding the codon circle. There is a lot of information there but it can actually be useful if you work with RNA or protein sequences.
