Students use the prelab as an introduction to the importance of DNA fingerprinting- a form of identification that us being accepted by both scientific and leagl experts. They prepare a gel for electrophoresis. DNA fragments, which have been predisgested using two different restriction enzymes, and run on a gel electrophoresis apparatus, and the results are analyzed to determine which suspect committed the crime.

Students are presented with a scenario that requires them to electrophoreses human hemoglobin samples in order to confirm a diagnosis of sickle cell anemia and/or to determine whether individuals in the scenario are carriers of the sickle cell allele. They are asked to analyze the separation of the different types of hemoglobin on the gel. Full Review »

Students analyze different types of hemoglobin. They use the technique of agarose gel electrophoresis to separate human hemoglobin molecules according to their electrical charge, size, and/or shape. Students relate the migration of hemoglobin molecules on the gel (phenotype) to the alleles possessed by individuals in the scenario (genotypes). Full Review »

Students create numbered DNA sequences by taping together the order of the sequence. They count the number of bases in their RFLP's and shade the boxes on their Gel Electrophoresis sheets that represent individual fragments. They compare their sequence to the baby DNA fingerprints to observe the differences in each other's DNA. Full Review »

Students are introduced to the principles of gel electrophoresis. They practice loading gels and pipetting. In this laboratory activity, food color is separated into constituent pigments. The lab can be run with standard electrophoresis equipment or with inexpensive homemade electrophoresis equipment. Full Review »
