Gel Electrophoresis and DNA Fingerprinting

Learn how to analyze DNA with this informative exercise! This two-page worksheet outlines the biotechnology technique of using gel electrophoresis to create a DNA fingerprint. Students are walked through the process of performing gel electrophoresis in a lab and how scientists can use the results for identification purposes. Growing scientists will then answer three questions about the technique.

Designed for middle-grade learners, this worksheet is a great introduction to gel electrophoresis and genetics. Students will learn to analyze diagrams and think critically about scientific processes.
