They learn fundamental molecular biology skills and concepts through a series of hands-on laboratory activities.
Students enjoy seeing their own DNA and learning how scientists can study it.
They then apply what they know about DNA profiling and Mendelian genetics to a real case study. They interpret DNA profiles and study behavioral data in order to determine why Harris' hawks form cooperative nesting groups in the Southwest United States. Cheek cells are collected from a salt water mouthwash, split open using detergent and heat, and the DNA is extracted. Students can keep their spooled DNA or resuspend it in solution for analysis by agarose gel electrophoresis. DNA Analysis by Agarose Gel Electrophoresis Students learn the basic techniques and concepts of agarose gel electrophoresis.
