You are analyzing DNA to determine which suspect was at a crime scene with a victim. You have PCR amplified short tandem repeats (STRs) from samples taken from the victim, two suspects, and the crime scene, and separated the PCR products via gel electrophoresis to perform “DNA fingerprinting” as follows. DNA sources are noted above each lane: Victim (Lane 1), Suspect 1 (Lane 2), Suspect 2 (Lane 3), and Crime Scene (Lane 4). DNA was loaded into wells at the top of the gel, near the lane-labels  (i.e. “Victim”, etc.).  Question:  Based on the data below, which suspect left DNA material at the crime scene? Please explain your choice, referring to specific band(s) on the gel. Copyright 2024 by Edmonds College Department of Biology. All rights reserved. Online sharing or distribution is prohibited.
