One integral characteristic of the set of genetic codes. The property of all known natural codes

Earlier, this author introduced the integral characteristics of the genetic code (“Integral characteristics of the genetic code,” Mathematical Modeling, vol. 22, no. 9, 2010). One of these characteristics that is correlated to the potential of a code for building overlapping genes, when the same piece of DNA encodes two protein sequences, is considered here. This is an investigation of a variety of genetic codes that corresponds to two groups of such codes. First of all, the hypothetical codes were considered and this has allowed the establishment of a range of changes in this characteristic by the use of different numbers of codon permutations in the standard genetic code. The second group of codes is the natural genetic codes. It has turned out that all of the known natural codes today (currently, 15) have one common property. This property is formulated. Note that the first natural standard code was found in the human cell in 1979, in a separate organelle—in mitochondria.
