The chemical structures that form the units of DNA and RNA and that encode genetic information i.e.the bases that make up the base-pairs are A, G, T, C and U ( see DNA). 形成DNA、RNA单体以及编码遗传信息的化学结构,也就是组成碱基对的碱基包括A、G、T、C、U。
Through statistic of base-pairs, it analyzes probability distributing and correlation of base-pairs. 通过对DNA序列中大量碱基的统计,对DNA序列中碱基对的概率分布和碱基对的相关性进行了分析研究。
