7th and 8th graders just started a unit on forensic genetics. After learning about the structure and function of DNA, they made their own edible DNA double helices. The Twizzlers represent the backbone of the DNA. The blue Sour Punch Straws represent Adenine. The green Sour Punch Straws represent Thymine. The pink Sour Punch Straws represent Cytosine. The red Sour Punch Straws represent Guanine. The bases always pair the same way (A and T, C and G), but work together in unique sequences to create unique life forms.
