ANALYSIS OF DNA SEQUENCE CONSTRUCTURE BASED ON NONLINEAR METHOD
基于非线性方法的DNA序列分析

The primary data based on the human DNA sequences were digitally coded. After the coded DNA sequence being ana lyzed by power spectrum, its self-comparability was further analyzed by using the Hurst index. The results show that the long range correla tion does exist in the DNA sequences, which relates to the DNA compo sition constructions. It denotes that the Hurst index of structural gr oup is larger than the Hurst index of functional group. At the same time, the long range correlation with intron content was also analyze d. The results show that the intron content is correlated differently with different chemical group in the same sequence. It indicates that the different chemical construction contribute to the DNA sequence characteristic differently. These conclusions suggest that it would be a new method to analyze the DNA sequence construction by nonlinear me thod.
