The Joint Multi-fractal Analysis of the Base Sequence of Chromosomes
染色体碱基序列的联合多重分形分析

The multi-fractal spectrum of the DNA sequence of a chromosome reflects its probability distribution, and the joint multi-fractal spectrum of two DNA sequences can be used to discriminate their distributions. By employing joint multi-fractal spectrum to analyze the DNA sequences of chromosomes and randomly generated sequences according to predefined distributions, it has been shown that, different chromosomes of the same specie can be viewed as being generated from the same information source, and chromosomes of different species can not be thought so, but all are different from randomly generated sequences. The joint multi-fractal can also be used in other fields for signal modeling and analyzing.
