In a first phase the 24 chromosomes of the Human are evaluated. In a second phase, 10 chromosomes for different species are also processed and the results compared. The results reveal invariance in the description and close resemblances with fractional Brownian motion.engDNASignal processingFourier analysisInformation theoryFractional calculusFractional Brownian motionjournal article10.1016/j.apm.2014.12.037
