DNA sequences are known to scale like fractals. We study coding
DNA and find, however, that these are not characterised by a
single scaling index. The behaviour changes, somewhat abruptly,
at about a few hundred bases. We study the Discrete Fourier
Transform and find that the index-change appears in the plot of
power spectrum vs. frequency. Interestingly, an
enhancement of the spectral density is observed in the region of
the index change. We study the peak heights at a frequency of
as a function of the length scale and find, once
again, changes in the scaling index near these critical lengths.
