摘要
在ＤＮＡ序列的研究中，序列的数值化是首先需要解决的问题。这里，提出了一种新的基于复域的映射规则，它以一维的形式反映了序列的多维组成：并分别从理论与实验两方面对该方法与已有的几种映射方法进行了对比与分析，论证了该方法的有效性及实用性。以此规则为基础，分析了外显子序列和内含子序列的编码结构和分形尺度特性，并以序列的编码结构—分形尺度特性—序列长度所构成的三维空间为基础，分析了外显于序列和内含子序列的可识别性。
In order to apply numerical methods to a nucleotide sequence, it is necessary to map it onto a numerical sequence corresponding to some certain ways. A new mapping rule based on the complex plane is proposed here. Its validity has been analyzed and compared with some existing mapping rules. It analyzes the holder exponent and the coding structure between hundreds of exon and intron sequences based on this mapping rule. It discusses the possibility of identification between exons and introns in 3D property space, composed of the holder exponent, die coding structure and the sequence length. The results are shown by the fitting surface.
