DNA extraction from plant tissue can be carried out by developing some steps common to different plant species. The function of each of these steps are described. Subsequently, the materials needed are presented. Last, the complete process is visualized using tomato leaves.
Type of Material:
Animation/video
Recommended Uses:
Best for lab use. Too detailed and technical for classroom use of DNA extraction principles, but excellent for teaching plant DNA extraction in the lab.
Technical Requirements:
The resource is accessible with most Internet browsers. Chrome works well.
Identify Major Learning Goals:
Users of this resource will learn the step-by-step process of extracting DNA from plant materials and understand the reason for using certain reagents and doing certain steps.
Target Student Population:
High School, College General Ed, College Lower Division, College Upper Division, Graduate School
Prerequisite Knowledge or Skills:
Need knowledge of DNA, basic cell biology, and chemistry and biochemistry knowledge. Also, knowledge of common lab skills and equiptment.
