Product Information Nearly three feet tall, this impressive DNA molecule model brings the microscopic world of the double-helix thundering into your classroom. Highly visible, it is perfect for lecture hall presentation, and features numerous components that provide effective hands-on investigations into the functional unit of heredity. Magnetic connectors permit the two strands of the double helix to unzip completely, dramatically evoking the mechanism of DNA replication and RNA synthesis. Removable nucleotides that use magnets to simulate hydrogen bonding, let your students experience why a larger purine base must always pair with a smaller pyrimidine base, and why base pairs are complementary. Supported on a hardwood stand, the model can be rotated for viewing from all angles. Measurements: 34” H x 16” D / 86 x 41 cm. Comes with instructional guide.  Tell a Friend about this item
