16s 核糖体DNA （rDNA）是细菌进化中比较稳定的,不太会变异.不同的细菌种类以及细菌的亚种间16s rDNA的某些片断存在一些差异.因此利用分析这种差异可以确认细菌的种类,细菌之间的进化等等.这即为16s rDNA的分析!
是16s rRNA分析吧???
16srRNA某些序列非常保守,而且16s rRNA的生理功能重要且恒定。所以一般在鉴定微生物，或分析进化上的亲缘关系时，常分析16s rRNA。
分析16s rRNA意思就是说分析其核苷酸序列。。。

The 16S rRNA gene is quite conserved among bacteria. Even though, there some difference between different organisms. Therefore, 16s rRNA is like a finger print: comparing certain locations on a 16s rRNA allows the identification of organisms. If a particular RNA doesn't match any known organism, then you know you have something new.
Also, the sequence of the 16S rRNA gene has been widely used as a molecular clock to estimate relationships among bacteria (phylogeny).
