Advanced—For experienced high school and college classes; requires some technical skill.

This advanced lab uses plasmid isolation and restriction analysis to illustrate forensic DNA typing. Students are provided with 2 samples of E. coli cells to represent blood samples from 2 suspects. Plasmid DNA is extracted using a miniprep procedure and cut with restriction enzymes, along with a DNA sample representing the evidence from a crime scene.

Advanced—For experienced high school and college classes; requires some technical skill.

Developed in cooperation with the DNA Learning Center, this advanced lab uses plasmid isolation and restriction analysis to illustrate forensic DNA typing. Students are provided with 2 samples of E. coli cells to represent blood samples from 2 suspects. Plasmid DNA is extracted using a miniprep procedure and cut with restriction enzymes, along with a DNA sample representing the evidence from a crime scene. The resulting "DNA fingerprints" of the suspects are compared for a match with the evidence.
