We study statistical properties of DNA chains of thirteen microbial complete genomes. We find that the power spectrum of several of the sequences studied flattens off in the low frequency limit. This implies the correlation length in those sequences is much smaller than the entire DNA chain. Consequently, in contradiction with previous studies, we show that the fractal behavior of DNA chains does not always prevail through the entire DNA molecule.
我们研究了13个微生物完整基因组的DNA链的统计特性。我们发现，所研究的几个序列的功率谱在低频极限处趋于平缓。这意味着这些序列中的相关长度远小于整个DNA链。因此，与之前的研究相反，我们表明DNA链的分形行为并不总是贯穿于整个DNA分子。
