Abstract
A DNA autocorrelation function is a slightly and slowly modulated autocorrelationfunction of a random sequence. Its coarse grained root-mean-squared fluctuationsare approximately homogeneous and equal to those of a random sequence. A DNAmay be decomposed into a random sequence of white noise domains, which havedifferent lengths and nucleotide concentrations, but a universal length scale.No long-range correlations are found in any of the studied DNA sequences.
