限制性内切酶可特异地结合于一段被称为限制酶识别序列的DNA 序列位点上并在此切割双链DNA 。绝大多数限制性内切酶识别长度为4、5或6个核苷酸且呈二重对称的特异序列，切割位点相对于二重对称轴的位置因酶而异。一些酶恰在对称轴处同时切割 DNA 双链而产生带平端的DNA 片段，另一些酶则在对称轴

DNA的限制性内切酶酶切(restriction－endonuclease，RE)分析
【原理】限制性内切酶(restrictionendonuclease，RE)是由细菌自己产生的能识别双链DNA分子中的特定碱基顺序，并以内切方式水解核酸中的磷酸二酯键的核酸水解酶。它可分为三种类型：Ⅰ、Ⅱ和Ⅲ型，Ⅱ型酶就是通常所指的RE，能识别双链DNA的特异顺序，并在这个顺序内进行切割。它是基因工

TRFLP的优缺点
该技术在应用的过程中，肯定需要在实验条件上不断进行改进，而这种改进的好坏自然而然需要实验结果的验证。。V. Grüntzig在2002年做了该工作的一部分，结果认为，在限制性酶切时，很有必要去除其中影响DNA的酶切过程，并且实验证明了具体的酶切时间。具有说服力的结果如下： 1，T-RFLP出数据的
