Yоu аre аnаlyzing DNA tо determine which suspect was at a crime scene. Yоu have PCR amplified short tandem repeats (STRs) from the samples and separated them via gel electrophoresis to perform "DNA fingerprinting" as follows. DNA sources are noted above each lane: Crime scene (Lane 1), Suspect 1 (Lane 2), Suspect 2 (Lane 3), and Suspect 3 (Lane 4). DNA was loaded into wells at the top of the gel, near the lane-labels (i.e. “Crime scene”, 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.
