Students perform agarose gel electrophoresis to analyze DNA samples from a mock crime scene.
This activity helps students understand how DNA variation in individuals can be analyzed in practical applications such as genetic testing and forensics. Each microtube contains 12 ul of the DNA sample. The high temperature keeps the agarose liquified. While the agarose is solidifying in the gel tray, the students can practice using the micropipet with the practice dye. After the gel is solidified and 1X TBE is added to the electrophoresis unit, students can practice loading the practice samples into wells.
