Use the model for demonstrations, or have your students participate in hands-on study of the DNA double helix. Either way, your students will be able to clearly view the details of the large model regardless of where they’re sitting. In addition, you can easily unzip the DNA to re-create RNA synthesis because the parts are attached with magnetic connectors that come apart easily. Atoms are color coded for easy identification. The model is mounted on a rotatable wooden stand and comes with an instruction manual. Size 34"H x 16" dia.
