Figure 7

Pair of genetic code chromosomes M', their quasi-identical correspondence can be seen horizontally, between the upper and the lower chromosomes and their chromatids (except M and W); the semi-introversion can be seen vertically, between the left side arms and the right side arms (where only the central nucleotides are reciprocally replaced, G for A (r by r) or C for T (y by y). Notice the uniform location of essential hydrophobic codons with T at the center in one left arm per chromosome.
