Whose DNA Was Left Behind?

NGSS-aligned with MS-LS3-A. DNA obtained from a single hair left behind at a crime scene can be used to identify a criminal. In this experiment, your students will compare simulated crime scene DNA with that of two suspects. • Learn about DNA fingerprinting while solving a crime! • Introduce the biotechnologies of restriction enzyme digestion, PCR, and electrophoresis • Perform agarose gel electrophoresis to separate different sized dye molecules • Load, run, and analyze simulated crime scene and suspect samples
