方法 对116例随机收集的1型糖尿病患者用聚合酶链反应-限制性内切酶消化作该点突变的筛选;
Methods The mutation had been screened from 116 unrelated patients with type 1 diabetes mellitus by ApaI digestion of product of polymerase chain reaction amplification.
If I cut both the plasmid and my DNA of interest with the same restriction enzyme I'm going to end up with the same sticky ends on both molecules.
如果用同一种限制性内切酶,来切割质粒和我感兴趣的DNA,在两个分子上就能得到同样的粘性末端
This gives you a biological mechanism for cutting, using restriction enzymes, and then you denature so that it falls apart, and then you renature so that it comes back together.
这是一种切割DNA的生物机制,用限制性内切酶,改变DNA的性质让它打开,然后让它合起来恢复它的性质
Well the first step would be to cut open the plasmid with a particular restriction enzyme, and then what if I take that same restriction enzyme and I cut up the DNA that I'm interested in.
第一步是用某种限制性内切酶把质粒切开,然后用同一种限制性内切酶,切出我想要的DNA
