    Area of Science:

    • Bioinformatics
    • Computational Biology
    • Genomics

    Background:

    • Nucleic acid sequences (DNA/RNA) are fundamental to genetics.
    • Identifying structural patterns within these sequences is crucial for understanding gene function.
    • Traditional sequence analysis can be complex and may obscure subtle patterns.

    Purpose of the Study:

    • To develop novel graphical coding methods for nucleic acid sequences.
    • To explore the utility of these methods in pattern recognition and sequence analysis.
    • To demonstrate the application of this coding in discriminating between introns and exons in a specific gene.

    Main Methods:

    • Representing the four nucleotide bases (Cytosine, Guanine, Adenine, Thymine/Uracil) with distinct graphical symbols.
