Nonlinear modeling technique for the analysis of DNA chains

Using a simple computational procedure, we examine DNA chains from differen t species in order to prove their nonlinear deterministic structures. This procedure applies a nonlinear modeling technique based upon quantitative co mparison of the neighborhoods from similar DNA subsegments of size d. Our r esults reveal that noncoding regions exhibit a deterministic signature at s izes larger than a characteristic dimension d(c). Applications to evolution ary categories and recognition of different DNA regions are discussed.
