In this activity, learners construct a model of DNA to better understand the structure of DNA and protein synthesis. First, learners follow simple instructions and an instructor's demonstration to create their DNA jewelry. Then, learners decode the model to identify the m-RNA bases, t-RNA bases, and amino acids that are encoded in their "DNA." Learners will enjoy constructing the models, which they can use as key rings, earrings, bracelets or necklaces. Materials can be purchased as a kit or individually.
