  Recent studies of DNA sequence of letters A, C, G and T exhibit the inverse
power law form. Inverse power-law form of the power spectra of fractal
space-time fluctuations is generic to the dynamical systems in nature and is
identified as self-organized criticality. In this study it is shown that the
power spectra of the frequency distributions of bases A, C, G, T in the Human
chromosome 1 DNA exhibit self-organized criticality. DNA is a quasicrystal
possessing maximum packing efficiency in a hierarchy of spirals or loops.
Self-organized criticality implies that non-coding introns may not be
redundant, but serve to organize the effective functioning of the coding exons
in the DNA molecule as a complete unit.
