This study introduces a Z(64)-algebra to model genetic mutations, revealing that most mutations in HIV protease and human beta-globin genes correspond to specific algebraic operations, aiding molecular evolution analysis.

Area of Science:

  • Bioinformatics
  • Computational Biology
  • Molecular Evolution

Background:

  • Codon-anticodon interactions are fundamental to protein synthesis.
  • Understanding genetic mutations is crucial for studying molecular evolution and disease.
  • Existing models may not fully capture the quantitative relationships in gene sequences.

Purpose of the Study:

  • To develop a novel algebraic framework, Z(64)-algebra, for analyzing genetic code and gene mutations.
  • To quantitatively describe gene mutation pathways using endomorphisms and automorphisms.
  • To investigate the nature of mutations in specific genes like HIV protease and human beta-globin.

Main Methods:

  • Constructing a codon array based on hydrogen bonds and base chemical types to represent interaction energies.

  • Introducing a sum operation on codons to form a group isomorphic to Z(64).
  • Applying endomorphisms and automorphisms within the Z(64)-algebra to model gene mutations.

    • Main Results:

    • The set of 64 codons forms a group isomorphic to Z(64).
    • Gene mutations can be effectively described as endomorphisms within this Z(64)-algebra.
    • A significant percentage (77.7%) of mutations in HIV protease gene sequences correspond to diagonal endomorphisms.
    • Most drug-resistant mutations in HIV protease and single codon mutations in human beta-globin genes align with automorphisms.

    Conclusions:

    • The Z(64)-algebra provides a powerful tool for analyzing genetic sequences and understanding mutation patterns.
    • This algebraic approach offers insights into the quantitative relationships governing molecular evolution.
    • The findings suggest that specific automorphisms and endomorphisms play a key role in genetic variation and adaptation.
