中文摘要：

分子生物学实验技术是现代生命科学研究工作中最基本的操作技术与实验手段，分子生物学实验所涉及的理论基础非常广泛，而且需要操作者具有一定的动手能力。而刚进入实验室的学生、研究人员在从理论走向实践的初学过程中常常发生各种“低级”错误。笔者收集了初学研究者在分子生物学实验过程中发生的一些常见问题，分析其原因，并对分子生物学实验教学提出了针对性的调整建议，以在实践过程中对这些错误及早发现和改正。

英文摘要：

Molecular biology experiment is the basic technic and means of modern life science research work. Molecular biology experiment involves diverse theoretical knowledge and requires the operator to possess certain practical ability. The students and researchers who have just entered the laboratory often make a variety of＂low-grade＂errors during the course from the theory to the practice. We collected common mistakes of beginner researchers in molecular biology experiment, analyzed its causation, and adjustment advice on molecular biology experiment teaching is proposed to early discover and correct these mistakes in the experiment practice.
