  The spatial distribution of DNA base sequence A, C, G and T exhibit
selfsimilar fractal fluctuations and the corresponding power spectra follow
inverse power law form, which implies the following: (1) A scale invariant eddy
continuum, namely, the amplitudes of component eddies are related to each other
by a scale factor alone. In general, the scale factor is different for
different scale ranges and indicates a multifractal structure for the spatial
distribution of DNA base sequence. (2) Long-range spatial correlations of the
eddy fluctuations. Multifractal structure to space-time fluctuations and the
associated inverse power law form for power spectra is generic to spatially
extended dynamical systems in nature and is a signature of self-organized
criticality. The exact physical mechanism for the observed self-organized
criticality is not yet identified. The author has developed a general systems
theory where quantum mechanical laws emerge as self-consistent explanations for
the observed long-range space-time correlations, i.e. the apparently chaotic
fractal fluctuations are signatures of quantum-like chaos in dynamical systems.
The model provides unique quantification for the observed inverse power law
form for power spectra in terms of the statistical normal distribution. In this
paper it is shown that the frequency distribution of the bases C+G in all
available contiguous sequences for Human chromosome Y DNA exhibit model
predicted quantum-like chaos.
