Easy to perform; requires some background knowledge.
- Introduces advanced concepts of PCR and DNA fingerprinting
- Gels can be run in 45 minutes with five 9-V batteries or overnight with 1 battery
- Introduces forensic techniques
This technically simple experiment simulates the use of DNA in forensic investigations. Students cast agarose gels, load predigested DNA, and perform electrophoresis. They use the banding patterns of the DNA in the gel to compare the DNA fingerprints of 2 suspects with evidence and victim DNA. Classroom Kit includes enough materials for 5 groups of students to perform the lab activity twice, plus it provides free 1-year access to digital resources that support 3-dimensional instruction for NGSS. Note: Order bulk DNA 2 weeks prior to desired ship date.
