Results of the Spring '11 Electrophoresis Experiment
aka. "Who killed Fred Flintstone?"
The students in Mr. Styer's Biotechnology class ended the "Forensics" and "DNA Technologies" units by conducting an experiment where the students:
Analyzed DNA evidence obtained at a crime scene
DNA evidence sample
5 suspects samples
Processed the DNA by adding EcoR1 restriction enzymes
Ran processed DNA through electrophoresis gel to separate fragments
Compared banding patterns to 5 known suspects
Match pattern from suspect to known evidence markers
The following are pictures of the experimentation process:
These are the resulting gels:
The first gel is just the result from the electrophoresis run.
The second is the same gel with the lanes properly labeled- the first lane is the crime scene. Look closely at the third suspect and you will see that the banding pattern matches the reference (crime scene) perfectly.
