We've been doing all sorts of things with genetics, punnet squares and heredity.One fun thing, while explaining DNA replication, was to make models of DNA out of leftover Halloween candy!
In these models, red licorice is the sense strand, and yellow is the non--sense strand. Fruit flavored tootsie rolls are the bases: cherry for adenine, blue raspberry for thymine, lime for cytosine, and grape for guanine. We used tooth picks to link everything together, and Laffy Taffy to make the zipping and unzipping enzymes.
