A numerical characterization of modified Hamori curve representation of DNA sequences
We present new numerical characterization of DNA sequences that is based on the modified graphical representation proposed by Hamori. While Hamori embeds the sequence into Euclidean space, we use analogous embedding into the strong product of graphs, K4 ~ P", with weighted edges. Based on this representation,anovel numerical characterization is proposed which is based onthe product s of ten eigenvalues from the start and the end of the descending ordered list of the eigenvalues of the Lj L matrices associated with DNA. The examination of similarities/dissimilarities among coding sequences of the first exon of the /3-globin gene of different species illustrates the utility of the approach.
