This study analyzes physico-chemical properties of codons and amino acids within the genetic code. It reveals fundamental patterns like codon periodicities and symmetries, linking them to the code's mathematical structure.

Area of Science:

  • * Bioinformatics and computational biology.
  • * Molecular biology and genetics.

Background:

  • * The genetic code translates nucleotide sequences into amino acid sequences.
  • * Physico-chemical properties of codons and amino acids are crucial for understanding protein structure and function.
  • * Previous studies have explored conformational parameters and genetic code structure.

Purpose of the Study:

  • * To systematically examine indices of physico-chemical properties of codons and amino acids.
  • * To identify and associate fundamental patterns within the genetic code with its underlying mathematical structure.
  • * To confirm and extend previous research on genetic code properties.

Main Methods:

  • * A numerical labeling scheme for nucleic acid bases (A, C, G, U) was employed.

  • * Physico-chemical data were fitted using low-order polynomials in a 64-dimensional codon weight space.
  • * Results were visualized using the Siemion one-step mutation ring scheme and its variants.

    • Main Results:

    • * The study successfully fitted genetic code data using polynomial representations.
    • * Fundamental patterns, including codon periodicities, harmonics, and reflection symmetries, were identified.
    • * These patterns were directly associated with the chosen basis monomials for polynomial fitting.

    Conclusions:

    • * The research confirms and expands upon existing knowledge of genetic code systematics.
    • * Identified patterns provide insights into the structural organization of the genetic code.
    • * Connections were established with studies utilizing dynamical symmetry algebras for genetic code analysis.
