 Quantumlike Chaos in Frequency Distribution of Base A, C, G, T in Drosophila DNA 
  The important result of the present study is that the observed fractal frequency distributions of the bases A, C, G, T of Drosophila DNA base sequence exhibit longrange spatial correlations or selforganized criticality generic to dynamical systems in nature. 
  A representative sample for the frequency of occurrence of base A in successive blocks of length 50 bases is plotted in Figure 1 for 10, 100, 1000 and 4500 segments for the total sequence consisting of 225000 bases used in the study. 
  The apparently irregular fractal fluctuations of the frequency distribution of bases A, C, G, T in Drosophila DNA base sequence selforganize spontaneously to generate the robust geometry of logarithmic spiral with the quasiperiodic Penrose tiling pattern for the internal structure.
