    The genetic code, a fundamental information system, exhibits universal characteristics. This study proposes a new optimization principle, incorporating information theory, to explain the origin and evolution of the genetic code.

    Area of Science:

    • Biochemistry
    • Molecular Biology
    • Information Theory

    Background:

    • The genetic code directs protein biosynthesis and is an information system with elucidated, yet not fully known, characteristics.
    • A universal structure with fundamental features suggests an underlying logic governing the genetic code.

    Purpose of the Study:

    • To interpret features of the genetic code table through a theoretical scheme based on resistance to mutations.
    • To extend existing optimization principles by incorporating Shannon's definition of information to model the origin and evolution of the genetic code.

    Main Methods:

    • Systematic approach to integrate features of the genetic code into a theoretical scheme.
    • Analysis of triplet and amino acid groups against mutation effects.
    • Extension of optimization principles to include information theory concepts.

    Main Results:

    • Many features of the genetic code table can be explained by a principle of optimal resistance against mutations.
    • A more general optimization principle, including information theory, is proposed.

    Conclusions:

    • The proposed generalized optimization principle offers a framework for understanding the origin and evolution of the genetic code.
    • Further exploration of this principle in simple models is warranted to elucidate the genetic code's complexities.
