Orbit Proview DNA Model-A great whole class activity - learn the chemistry and structure of DNA. Engage students as they work together to create the sub-assemblies and then fit the model together. Build and study the composition of the sub-assemblies: Thymine-Adenine, Cytosine-Guanine, sugar rings and phosphate groups .See the chemical structure: each atom is colour-coded, with the correct bonding angles . View the structure: 12 base pairs show more than one turn of the double helix and major and minor groves . Understand the different types of bonding: different colours indicate covalent or hydrogen bonding . The open structure enables students to see the constituent parts and their chemical composition . Large scale enables group viewing and demonstration. Easy construction: attach the sub-assemblies onto pre-assembled atom pieces on the nylon wires for a spectacular end result Dimensions: 85 x 35cm (HxW)
