    Area of Science:

    • Biophysics
    • Molecular Biology
    • Biochemistry

    Context:

    • Nucleic acids possess complex tertiary structures crucial for their function.
    • Small molecules like antibiotics and dyes can interact with nucleic acids.
    • These interactions can potentially alter the nucleic acid's structure and internal energy.

    Purpose:

    • To develop a model describing the binding of small molecules to nucleic acids.
    • To investigate how binding affects nucleic acid tertiary structure and internal energy.
    • To establish relationships between internal energy and the degree of ligand binding.

    Summary:

    • A computational model is presented for analyzing the binding of antibiotics and dyes to nucleic acids.
    • The model accounts for alterations in nucleic acid tertiary structure and internal energy upon small molecule binding.
    • It derives relationships to quantify the dependence of internal energy on ligand binding extent, impacting binding isotherms.

    Impact:

    • Provides a framework for understanding structure-activity relationships in drug-nucleic acid interactions.
    • Enhances the interpretation of binding isotherms for nucleic acid-ligand systems.
    • Facilitates the design of novel therapeutic agents targeting nucleic acid structures.
