Fingerprints are not just random lines on your fingers, they are specific, detailed and your own. /// Use gel electrophoresis to solve a crime! Perfect for teaching students to use DNA technology in a STEM STEAM class or in Biology or Forensics.
Each group is given a long paper strip of DNA, a story of the missing necklace and directions on how to fingerprint and sequence their DNA. Scissors act as the restriction enzyme, cutting the DNA between every CCGG into varied length segments.
Gel electrophoresis is a powerful technique used to manipulate DNA and as an analytical tool, such as in DNA fingerprinting. Build your own gel electrophoresis device from scratch with simple materials, and use electricity to separate colored dyes.
