Use evidence found in DNA fingerprint patterns to argue which suspect committed a crime.

Intermediate—Easy to perform; requires some background knowledge.

Solve a forensic mystery using the tools of biotechnology and the concept of DNA fingerprinting. Students cast agarose gels, load predigested DNA samples, and perform electrophoresis with one to three 9-V batteries. They stain the gels and analyze the banding patterns of DNA collected from the suspects and the crime scene. Classroom Kit includes beautifully illustrated instructions, free 1-year access to digital resources that support 3-dimensional instruction, as well as needed materials and equipment for 5 groups of students to perform the lab twice. Materials are durable and reusable with replacement parts available.
