DNA Fingerprinting 1
DNA fingerprinting has received a lot of attention as a forensic investi- gative tool. Already a deciding factor in numerous criminal cases, this technique can be effectively demonstrated in the classroom. This labo- ratory will illustrate the basic principles of DNA fingerprinting, with the results being analyzed and discussed in terms of a hypothetical criminal case. DNA samples from two suspects, each cleaved with two different restriction enzymes, are electrophoresed on a gel along with samples taken from the crime scene. Analysis will determine the guilty party.
Requires electrophoresis apparatus, balance, power and heat supply, and white light visualization system. Components need refrigeration. Enough materials for 4–6 runs. DNA source is Lambda phage.*
DNA Fingerprinting—Electrophoresis
at Work—Super Value Kit
By: The Flinn Staff
An introductory activity for students about to begin the study of biotechnology and electrophoresis. Students become medical forensic investigators as they read a case in which a woman has been attacked or a case in which an elderly man has been murdered. Once the students have read one of the case reports, they are provided with photo- reproductions of actual electrophoresis gels. Students will interpret the evidence against a list of possible suspects and attempt to solve the mystery. The design of the activity affords the teacher the flexibility to alter case outcomes from class to class and even manipulate evidence. Kit includes in-depth background material, preparation and instruc- tion tips, student copies of case descriptions and investigation reports, and reproductions of evidence and suspect electrophoresis gels. The curiosity and excitement this activity creates will lead to a better under- standing of electrophoresis and biotechnology. Time required for this activity is 30 minutes.
Super Value Kit is complete for 30 students working in pairs. All materials are reusable.
A Murder Mystery—DNA Fingerprinting—
Super Value Laboratory Kit
By: The Flinn Staff
A murder has occurred, and DNA samples from various suspects have been collected. Challenge your class to solve the mystery using simu- lated DNA fingerprinting techniques. With this completely reusable kit, students match “pop bead” DNA fingerprints of the suspects with samples collected at the scene of the crime. Students learn:
• The basics of DNA fingerprinting
• DNA structure and extraction
• Gel electrophoresis and autoradiography • The accuracy of DNA fingerprinting
Super Value Kit is complete for 30 students working in investigative teams of 10 students.
