主 题:Autocorrelation function DNA sequence Long-range correlation.
摘 要:The characterization of long-range correlations and fractal properties of DNA sequences has proved to be adifficult though rewarding task mainly due to the mosaic character of DNA consisting of many patches of various lengthswith different nucleotide *** this paper we investigate statistical correlations among different positions in DNAsequences using the two-dimensional DNA *** root-mean-square fluctuation F(l)is described by a power *** function C(l),which is used to measure the linear dependence and periodicity,exists a power law ofC(l)-l^(-μ).We also calculate the mean-square distancealong the DNA chain,and it may be expressed as-l^(?)with 2γ*** investigations can provide some insights into long-range correlations in DNA sequences.
