DNA Evidence
Kastle-Meyer Reagent—Forensic Test
Simply wipe a presumptive bloodstain with a cotton swab, add a drop
of the reagent, and then apply a drop of hydrogen peroxide. If the
swab turns pink rapidly, it is positive for blood! For a terrific guidedinquiry
forensic activity, use the Kastle-Meyer reagent to investigate
substances that will interfere with the test to give false positives.

Who’s the Daddy? DNA
Profiling—Super Value Kit
By: The Flinn Staff
Students cut fragments to simulate restriction enzyme digestion and then separate
the fragments by size in a simulated gel. Next the DNA fragments are “denatured”
(cut into single strands), “blotted” (pattern copied onto a sheet of paper) and treated
with simulated radioactive probes that combine with only specific base sequences.
Includes black-line masters of simulated DNA segments, “radioactive probe” locators,
electrophoresis gel blotter, magnetic tape and zipper-lock bags.
Super Value Kit is complete for 30 students in groups of 6. All materials are reusable.

DNA Fingerprinting 1
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
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, teacher preparation and instruction tips, student
copies of case descriptions and investigation reports and reproductions of evidence
and suspect electrophoresis
gels.
Super Value Kit is complete for 30 students working in pairs. All materials are
reusable.

at the scene of the crime. Students learn the basics of DNA fingerprinting, DNA
structure and extraction, gel electrophoresis and autoradiography and the accuracy
of DNA fingerprinting.
Full-size kits are complete for 30 students in groups teams of 10 students. Smallsize

A Case of Abduction—DNA
Identity Testing Simulation
By: William Humphries, Richardson H.S., Richardson, TX
• “Digest” short, 60 base-pair sequences of mitochondrial
DNA using Hae III restriction enzyme.
• Determine the sizes of the resulting “fragments”
and use a standard curve to plot the migration
distance for each fragment on a paper “gel.”
• Label the separated fragments with a “radioactive
probe sequence.”
• Interpret the results to determine the true parentage of a child.
Includes extensive background information, objectives, reproducible student copy
masters, detailed results, study and follow-up questions, glossary and extension
ideas. The activity is designed to be conducted by cooperative teams and can be
completed in two class periods.

Dyeing for Forensics—
Super Value Laboratory Kit
By: The Flinn Staff
Six simulated DNA samples are analyzed using gel electrophoresis to determine which
family described in the scenario is entitled to receive the mementos and money. This
activity is a simulation of the type of analysis made using DNA fingerprinting with two
special cases of relatedness testing—Y chromosome and mitochondrial DNA testing—
newer methods often used on old or degraded DNA. Since simulated DNA is used, the
dyeing step is not necessary. Colorful bands are visible after the gel has run for 15–20
minutes, and results are read during the same lab period.
Complete for 20 gels. Requires electrophoresis apparatus and power supply.
