Ward's® DNA Fingerprinting Electrophoresis Lab Activity

Explore basic elements of forensic science.

• Includes key materials to perform gel electrophoresis
• Battery-powered gel electrophoresis
• Applications to forensics and genetic testing
• Time Required: 120 minutes (60 minutes if using 10 batteries)
• Aligned to NGSS standards (MS/HS: LS1, LS3)

DNA fingerprinting can be used to identify the perpetrator of a crime, determine familial relationships, track hereditary diseases passed down in families, find a close match for an organ transplant, and more. With this electrophoresis system, students can perform the same type of gel separation used in these analyses in approximately two hours; students are given DNA samples from a “crime scene” to electrophorese and discover who perpetrated the crime by analyzing their unique genetic patterns or fingerprints.

Each group loads one well.

The kit is also available for purchase with a link to a NewPath digital lesson, which includes a variety of resources on the topic, including background information, illustrations and self-assessments.
