Genomic signature: the mathematical functions associated with it

Extensive data analyses support the proposal that each living organism possess a genomic signature consisting of oligonucleotide relative abundance values calculated from genomic sequences. The Chaos Game Representation shows that the core features characterizing the whole genome are preserved in short subsequences of it, validating the idea of a genomic signature. This paper present an alternative approach to the genomic signature detection. Although ensuring the same information retrieved from classical methods, it presents the advantage to be conceptually very simple and computationally less expensive.
