By mapping nucleotide sequences onto a "DNA walk", we uncovered remarkably
long-range power law correlations [Nature 356 (1992) 168] that imply a new scale
invariant property of DNA.  We found such long-range correlations in
intron-containing genes and in non-transcribed regulatory DNA sequences, but not
in cDNA sequences or intron-less genes.  In this paper, we present more explicit
evidences to support our findings.
