About This Product
DNA from a single hair left at a crime scene can be enough to identify a criminal. This kit turns that idea into a practical: students run the simulated crime scene DNA beside samples from two suspects and decide whose DNA was left behind. A practice gel loading solution is included for rehearsing the loading step.
