Abstract
We study statistical properties of DNA chains of thirteen microbial complet e genomes. We find that the power spectrum of several of the sequences stud ied flattens off in the low frequency limit. This implies the correlation l ength in those sequences is much smaller than the entire DNA chain. Consequ ently, in contradiction with previous studies, we show that the fractal beh avior of DNA chains does not always prevail through the entire: DNA molecul e. [S1063-651X(99)10211-3].
