DNA的粗提取与鉴定实验方案的改进与探讨

The Improvement and Discussion of DNA Rough Extraction and Identification

DNA的粗提取与鉴定是高二生物课程中一个重要的实验,从鸡血中提取DNA,材料难得,操作比较复杂,实验的成功率较低。文章针对导致实验失败的原因进行了探讨,改进操作步骤,解决了实验中存在的问题,最后获得了理想的实验效果。

The rough extraction and identification of DNA is an important experiment in biology curriculum of senior two. DNA was isolated from chicken blood which can be scarcely obtained. The operation of the experiment was complex, and the success rate was also lower. The paper disscussed the reasons of failure, improved the steps of operation and solves the problems in the experiment. Ideal experimental effect acquired at last.
