基于密码对使用的基因组进化
Analysis of genome similarity based on codon-pair usage
摘要
Abstract
The phylogenetic trees are constructed using the codon - pair usage bias and the dinucleotide frequencies within codon - pairs. A phylogenetic tree constructed using the dinucleotides frequencies within codon - pairs in 40 mode organisms shows that the organisms are apparently divided into three evolutionary groups, Bacteria, Archaea,and Eukaryota. Another phylogenetic tree constructed using the index reflecting codon - pair usage bias is consistent with the phylogenetic tree constructed based on the dinucleotides frequencies within codon - pairs. Our results indicate that the component of dinucleotides within codon - pairs is one of the determinants of codon - pair bias.关键词
