| 摘 要： | Using continuous wavelet transform as the analytical tool,the fractal characteristic of nucleotide sequences was studied.The fractal dimension of the exon and intron sequences for different species was calculated.We use the Mexican hat wavelet function as the mother wavelet and Hurst exponent describe the long-range correlation.It is found that the Hurst exponent of intron sequence is larger than of exon sequence for the same gene.

| Abstract: | Using continuous wavelet transform as the analytical tool, the fractal characteristic of nucleotide sequences was studied. The fractal dimension of the exon and intron sequences for different species was calculated. We use the Mexican hat wavelet function as the mother wavelet and Hurst exponent to describe the long-range correlation. It is found that the Hurst exponent of intron sequence is larger than that of exon sequence for the same gene. |
