E.coli和Yeast基因起始与终止密码子邻近序列碱基保守性、关联性的对比研究

The Contrast Study of Base′s Conservative Character and Correlative Character between E.coli and Yeast Gene for Adjacent Sequence of Initiation Codon or Termination Codon

计算E .coli和Yeast基因起始与终止密码子邻近序列单碱基、相邻双碱基、相邻三碱基的碱基出现概率得出的M1(l)、M2 (l)、M3 (l)值 ,很好地体现了原核生物E .coli和真核生物Yeast翻译起始区域的显著差异 ;矩阵P的本征值之和 ,可作为衡量不同生物基因碱基保守性、关联性强弱程度的一个指标 .

The values of M 1(l)、M 2(l) and M 3(l) are obtained by calculating probability of single base, neighbor 2 bases and 3 bases near initiation codon and termination codon. The remarkable difference between prokaryote E.coli and eukaryote Yeast at translation region is reflected. The sum of matrix P eigenvalues can be used as a index of measuring degree of conservative character and correlative character of different living things′ genes.
