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 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 »
