This paper represents the preliminary results and conclusions on the one of
fundamental questions of the genetic code related to the underlying selective
mechanisms involved in its origin and evolution, in particular their
hypothetical different nature, originally considered in [1,2,3]. A novel
approach is introduced, based on known arithmetic regularities inside the
genetic code, determined by the nucleon balances of amino acids and their
divisibility by the decimal number 37 [4]. As a parameter of the genetic code
systematization is introduced an aggregate nucleon number of amino acid and
cognate codon, while divisibility test is carried out not only by the number
37, but also by 13.7, the selfsimilarity constant of decimal scaling [5].
Relevant nucleon sums were obtained for the most prominent divisions of the
standard genetic code (SGC) according to p-adic model of the vertebrate
mitochondrial code (VMC) in [6]. The nucleon number divisibility pattern of
37 and 13.7 for the RNA and DNA codon space, as well as for the amino acid
space is also analyzed. The obtained results, particularly a general higher
divisibility of the nucleon sums by the numbers 37 and 13.7 in SGC than in
VMC, as well as a correspondence between the nucleon number divisibility
pattern of both the RNA codon space and the amino acid space of SGC, how
separately so conjointly, with the code degeneracy pattern, suggest some
conclusions: support the hypothesis [1,2,3,7] that the selective driving
forces acting during an emergence (an ancient phase) and an evolution (a
modern phase) of the genetic code are different, imply the existence of an
environmental-dependent stereochemical mechanism throughout the entire period
of the genetic code emergence and support a mineral-mediated origin of the
genetic code [7,8].
