Development of Molecular Biology Laboratory Exercises for Large Introductory Biology Classes

生物学专业的学生必须学习分子生物学的理论基础，并获得在这一极其重要且迅速发展的领域中使用的方法的实践经验。这个项目将在加州大学圣巴巴拉分校的生物学实验室入门课程中设立一个分子生物学教学单元。本单元由两个三小时的实验室练习组成，其中学生将探索从完整细胞中提取DNA、限制性内切酶消化、DNA的电泳分离和DNA片段大小分析，以及一个小时的计算机辅助限制图谱练习。

Students of biology must learn the theoretical basis of molecular biology and also acquire practical experience with the methods used in this critically important and rapidly expanding field. This project will establish an instructional unit in molecular biology in the Introductory Biology Laboratory Curriculum at the University of California at Santa Barbara. This unit is composed of two three-hour laboratory exercises, in which students will explore extraction of DNA from intact cells, restriction endonuclease digestion, the electrophoretic separation of DNA, and analysis of DNA fragment size, and a one-hour computer-assisted restriction mapping exercise.
