  • Visualization and clustering of DNA sequences
    Rizman Žalik, Krista
    Visual inspection can discover pattems that are quite difficult to discover with computers. We introduce a novel encoding algorithm providing graphical representation of DNA in order to characterize ... and compare long DNA sequences. The algorithm transforms a DNA sequence into four encoded sequences of natural numbers describing all the distances between each two the same and nearest nucleotides in a DNA sequence. Encoded DNA sequences of natural numbers are simpler for computer handling and numerical analysis, and can be employed for 2D graphical representations that offer visual analysis. This novel representation for processing DNA sequences is demonstrated using the coding sequences of the ▫$\beta$▫-globin gene's exon I for eleven different species. Similarity analysis was done by means of ID and 2D representation and numerical analysis with similarity/dissimilarity measures used for clustering.
