Noisy Levy walk analog of two-dimensional DNA walks for chromosomes of S-cerevisiae

The DNA sequences of all the chromosomes of Saccharomyces cerevisiae are mapped onto a d = 2 space. The resulting patterns are interpreted as a two-dimensional walk. Their mean square displacement shows a superdiffusive behavior. We address the question if this behavior can be understood in terms of a random walk model. We found that it can be modeled as a superposition of a Levy walk and white noise.
