Background: Scientists use a technique called gel electrophoresis to look at a DNA fingerprint. The DNA separates into bands and these bands form different lengths. Every organism, with the exception of identical twins, has a different DNA fingerprint.
Goal: To understand how DNA is separated into a fingerprint by using a chromatography activity to simulate gel electrophoresis.
Learning Objectives: Students will…
- Follow directions to complete a gel electrophoresis simulation
- Use a color-separation technique to separate individual colors from two sample solution
- Use the results of the separation to infer whether the sample solutions are identical or not
