聚类分析方法在DNA序列分类中的应用

摘要

从DNA序列片段个案中密码子分布密度角度出发，提取出DNA序列片段的特征，基于五大类氨基酸出现的频率，应用聚类分析方法对DNA序列片段进行分类．结果表明，该算法具有分类简单且分类结果精度较高的优点。%From the distribution density of each codon of DNA sequence, the feature of DNA sequence frag- ment is extracted, and DNA sequence fragment is classified using the cluster analysis method based on the frequency of five kinds of amino acid The results show that this method is simple in classification and accurate in the precision of classification results.
