Most individuals of the same species, whether African elephants, portobello mushrooms, white oak trees, or
humans, have nearly identical DNA. But the DNA sequence at certain locations, or loci, throughout the genome
varies among individuals. These variations can be used to distinguish one individual from another of the same
species. The process of analyzing these DNA variations for the purpose of identification is known as DNA profiling,
or genetic fingerprinting.
The graphic below represents a gel electrophoresis that was run during a crime scene investigation to create a DNA profile. Column 1 represents DNA found at the scene of the crime. Columns 2-5 are DNA samples obtained from suspects.
Analyze the DNA profile evidence obtained from gel electrophoresis by completing the following questions:
Identify which suspect(s) can be excluded.
Identify which suspect(s) cannot be excluded.
