    "abstract": "By using the Jensen-Shannon divergence, genomic DNA can be divided into\ncompositionally distinct domains through a standard recursive segmentation\nprocedure. Each domain, while significantly different from its neighbours, may\nhowever share compositional similarity with one or more distant\n(non--neighbouring) domains. We thus obtain a coarse--grained description of\nthe given DNA string in terms of a smaller set of distinct domain labels. This\nyields a minimal domain description of a given DNA sequence, significantly\nreducing its organizational complexity. This procedure gives a new means of\nevaluating genomic complexity as one examines organisms ranging from bacteria\nto human. The mosaic organization of DNA sequences could have originated from\nthe insertion of fragments of one genome (the parasite) inside another (the\nhost), and we present numerical experiments that are suggestive of this\nscenario.",
