title: Vector representation and its application of DNA sequences based on nucleotide triplet codons.
abstract: Compared with single nucleotide, nucleotide triplet appears to contain more biological and genetic information, so it has been applied widely. We propose a new 3D-vector representation method of DNA sequences, namely use molecular weight of nucleotide triplet to define the '0' molecular plane, then make the 3-D coordinate transformation to map a DNA sequence into a curve by the coordinate accumulation, and then extract the D/D matrix's eigenvalues to describe, compare and analyze the DNA sequences as the numerical characterization. It is a new idea for comparison and phylogenetic trees' reconstruction of biological sequences.
