First, many graphical representations were designed by assigning the single bases or dual nucleotides to corresponding direction/points/cells in Cartesian coordinates, so little attention has been paid to the whole distribution of the single nucleotide or dual nucleotides in biological sequences. Based on the whole distribution of the dual bases, we proposed a polar coordinates representation that maps a biological sequence into a closed curve. Here, we propose a novel graphical representation of DNA sequence in polar coordinates based on the distribution of the dual nucleotides. In contrast to the existing graphical representations, we used the whole distribution of the dual bases to map a biological sequence into a closed curve in polar coordinates.
