DNA Activity Model
Product Code : JLI-BLE-10676
Quick Answer: The DNA Activity Model is a DNA model kit from which students build a three-dimensional double helix with colour-coded cytosine, adenine, guanine and thymine bases on a metal base that rotates for display.
Last updated: 18 October 2026
Key Features
- Students assemble their own double helix model.
- Includes cytosine, adenine, guanine and thymine bases, connecting phosphate strands and a centre rod representing hydrogen bonds.
- Colour-coded parts with specially shaped ends so bases pair correctly.
- The helix can be unzipped to demonstrate DNA replication.
- Durable plastic components on a sturdy metal base for rotation and classroom display.
Technical Specifications
| Specification | Value |
|---|---|
| Bases | Cytosine, adenine, guanine, thymine |
| Other parts | Connecting phosphate strands, centre rod representing hydrogen bonds |
| Material | Plastic components |
| Base | Metal, allows rotation |
| Dimensions | 130 x 130 x 450 mm (approx.) |

How It Is Used
Students fit the colour-coded bases onto the phosphate strands, matching the shaped ends so each base pairs with its partner, and build the helix around the centre rod. Once complete, the model can be turned on its base for display or unzipped to show how DNA separates during replication.
Frequently Asked Questions
