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. Materials are sufficient for 6 teams of students or 6 teacher demonstrations. Foreign orders require special handling. Sold only to schools and businesses.
FREE 1-year access to digital resources that support NGSS instruction included.
