Why Lesson Planet?
Seventh-graders come in to science class to find a file on their desks detailing a crime to be solved! As a demonstration, you simulate the restriction of DNA samples and separate them by electrophoresis. From the gel, learners can determine the culprit. The procedures assume that you are familiar with restriction enzyme digestion and gel electrophoresis; details are left out. Unfortunately, what is contained in the fictitious crime is not provided either.
