The question shows the results of a gel
electrophoresis, which shows DNA fragments of the victim and two suspects,
suspect 1 and suspect 2. A comparison of the five DNA fragments of the victim,
A to E, reveals that the victim and suspect 1 both have the DNA fragment b.
A
visual comparison of the gel electrophoresis results should reveal that Suspect
1 has a DNA fragment that matches victim DNA fragment B.<span>The visuals can be seen in the attachment.</span>
