Genomic data visualization

The sequencing of DNA implies an exponentially growing number of genomic data. This mass of information requires excessive work to reveal the location and functions of the characteristic areas in the genomes. In order to make exploratory studies, the alphabets of a DNA sequence need to be mapped onto their corresponding numerical values for visualization and analysis. This paper develops and compares a number of one dimensional and two dimensional mapping approaches. These coding techniques involve the alignment of bases in the polypeptide chains or affect the 3D structure of the DNA molecule.
