Abstract
A new method of quantifying correlations in symbolic sequences
is applied to DNA nucleotides. Spectral density measurements of
individual base positions demonstrate the ubiquity of low-frequency
1/f^beta noise and long-range fractal correlations as well as prominent
short-range periodicities. Ensemble averages over classifications
in the GenBank databank (primate, invertebrate, plant, etc.) show
systematic changes in spectral exponent beta with evolutionary
category.
