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. Demo 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 1 instructor to perform the demonstration twice to a classroom. Materials are durable and reusable with replacement parts available.
