摘要
根据外显子在密码子三个位点上的分布不均匀性 ,引入非均匀指标 H I,来研究线虫基因外显子与内含子的序列特征 .通过推广 H I参数 ,定义干涉指标 R,对外显子和内含子的多个片段的特征进行研究 ,得到了 R值分布以及与外显子和内含子片段的关系 .
Base on the heterogeneity of bases distribution of exon on three codon sites,the heterogeneity index HI is introduced and used in the study of the sequence peculiarity of exon and intron in C elegans.By generlizing parameter HI ,the interference index R is defined.The character of several sequence segments of exon and intron is studied by use of R, and the relation between the distribution of R and the number of sequence segments of exon and intron is gained.
