Nonlinear modeling technique for the analysis of DNA chains

Using a simple computational procedure, we examine DNA chains from different species in order to prove their nonlinear deterministic structures. This procedure applies a nonlinear modeling technique based upon quantitative comparison of the neighborhoods from similar DNA subsegments of size d. Our results reveal that noncoding regions exhibit a deterministic signature at sizes larger than a characteristic dimension $d_c.$ Applications to evolutionary categories and recognition of different DNA regions are discussed.
