Forensic DNA Banding Patterns

Abstract

Understanding how DNA banding patterns in a gel can aid in the conviction or exoneration of suspects and be utilized for positive identification of biological fathers in paternity cases can be intimidating. In reality, the logistics and technology used in such cases are rather straightforward. This exercise is designed for use in high school environments as a stand-alone paper lab and as a primer to an actual wet-lab experience, if available. Upon conclusion of the experience, students will have confidence in understanding how DNA fingerprinting can constitute strong evidence in forensic analysis.
