That's an example of symmetric sequence and it happens that most restriction enzymes also recognize those spaces.

这是一个对称序列的例子,大多数限制性内切酶都能识别这些序列

They do that in a very special way in that they - restriction enzymes are able to identify a particular sequence of bases in a gene.

限制性内切酶的工作机制很特别,它能识别基因中的一段特定的碱基序列

It takes advantage of the specificity of the restriction enzymes, the fact that we know what the gene sequence that we're looking for, and using this technological process of electrophoresis to identify changes that we predict.

这个方法利用了限制酶特有的性质,我们知道我们在找什么样的基因序列,从而才能利用电泳这个技术流程,来识别出我们预计的情况

Most restriction enzyme also recognize symmetric sequences of DNA, GAATTC for example.

大多数限制性内切酶,也能识别DNA的对称序列,例如GAATTC

This particular restriction enzyme here recognizes this sequence,GAATTC.

这里的这种限制性内切酶,只识别序列GAATTC

Well one way you could do it is by saying 'if I have this one base pair difference then this sequence is going to be cut by a specific restriction enzyme that recognizes the sequence CTGAGGA'.

一种方法是通过考虑,"如果我有这个不同的碱基对,那该序列必然会,被特定的限制酶识别并切割,这个特定的限制酶能识别,CTGAGGA "
