Abstract
Spectral density and random walk methods of analyzing symbolic
sequences, such as DNA bases, are compared. Systematic errors in
DNA walk analysis, wide variability between samples, and small
ensembles cast doubt on previous conclusion that long-range
correlations in DNA occur in non-coding (intron) sequences.
A new study of all GenBank release 73 annotated features
demonstrates that both introns and exons have similar long-range
fractal correlations with exponents consistent with previous
category average.
