Yоu аre аnаlyzing DNA tо determine which suspect was at a crime scene with a victim. Yоu 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: Some of your bands in lab looked brighter than others; similarly, some bands in this gel are thicker than others. If one band looks thicker (or brighter) than another, what does this tell us about this thicker band, i.e., why is it thicker? A sentence or two should suffice.
