DNA Double Helix Model, 22 Segments
Product Code : SCL-PLE-12454
The JaincoLab DNA double helix model (SKU SCL-PLE-12454) is a molecular model set for building a right-rotating double helix of 22 segments. Colour-coded parts represent the four nitrogen bases, the deoxyribose sugars and the phosphate groups, so students can see how the molecule is put together and how the bases pair. It can also be used to model DNA replication, and it suits biology lessons in secondary schools and colleges.
Specifications
The set builds a right-rotating double helix and is supplied with assembly instructions and a stand. The assembled model measures 44 x 11 x 11 cm and weighs 0.5 kg. The part counts from the product data are listed below.

Applications of the DNA double helix model
Building the helix by hand helps students remember the order and pairing of its parts. The model is used for:
- Showing the structure of DNA: bases, sugars and phosphate groups
- Demonstrating complementary base pairing (A with T, G with C)
- Modelling DNA replication
- Genetics and molecular biology lessons in secondary school and college
