Several mathematical tools are selected to establish a quantitative method without distorting the alphabet represented by the sequence of DNA bases. The association of Gray code, Fourier transform and fractional calculus leads to a categorical representation of species and chromosomes.engDNAFractional calculusFourier analysisjournal article10.1016/j.cnsns.2010.11.007
