    This study introduces a novel algorithm for comparing restriction maps, quantifying differences and aligning them. It calculates the minimum genetic events needed to transform one map into another, aiding evolutionary studies.

    Area of Science:

    • Bioinformatics
    • Computational Biology
    • Molecular Evolution

    Background:

    • Restriction mapping is crucial for analyzing DNA.
    • Comparing genomic regions across species reveals evolutionary insights.
    • Existing methods may not efficiently quantify map differences.

    Purpose of the Study:

    • To develop a new algorithm for comparing restriction maps.
    • To quantify the distance and align two restriction maps.
    • To identify minimum genetic events for map conversion.

    Main Methods:

    • Developed an algorithm to compare restriction maps.
    • Calculated minimum weighted sum of genetic events (site changes, base pair alterations).
    • Applied the algorithm to the globin gene cluster in four primate species.
