A fun and exciting laboratory activity for isolating human genomic DNA and creating wearable DNA necklaces. Following a simple procedure, students extract crude DNA from their own cheek cells. They lyse their cheek cell sample and watch as wispy white strands of their own DNA precipitate out of solution in the presence of ethanol. After transferring the DNA to plastic microcentrifuge tubes, students fashion the tubes into DNA pendant necklaces using colored string. Suitable for middle school through college students. Kit includes enough materials for a class of 32 students.

Kit includes:

• Cell Lysis Solution
• Ethanol (70%)
• Sports Drink
• Plastic Pipets
• Pendant Tubes
• Small Plastic Cups
• 15-mL Tubes
• Colored String
• Teacher's Manual with Reproducible Student Guide
