DNA Structure Model, Plastic Assembly Kit
Product Code : LSK-HSM-10989
DNA Structure Model, Plastic Assembly Kit (SKU LSK-HSM-10989) is a 12 base pair DNA model built from specially shaped, brightly coloured plastic pieces that students assemble into a double helix and then pull apart into two strands. It suits hands-on genetics work in senior school, undergraduate and teacher-training classes. Science Lab Supplies produces the kit at its manufacturing unit in Saha, Ambala, India (Plot 448, HSIIDC Industrial Area) and quotes it to schools, colleges and stockists.
Specifications
All specifications of the 12 base pair kit are set out below. In short, each base has a subtly different shape, the sugar pieces are moulded from a slightly different plastic so the assembled model flexes into a true double helix, and the finished model measures 12 x 12 x 40 cm.

Applications and Experiments for the DNA Plastic Assembly Kit
Students build the double helix piece by piece, which makes base shape and pairing tangible, then move the central spine and pull the strands apart along the hydrogen bonds to model the first step of replication. It fits NCERT Class 12 Molecular Basis of Inheritance and B.Sc. genetics practicals.
- Class 12 biology: complementary base pairing and the double-helix structure, built rather than only viewed.
- Replication lessons: separating the two strands, then relating DNA copying to the stages on the Cell Reproduction-Mitosis wall chart.
- Class 11–12 chemistry: hydrogen bonding between base pairs, alongside general sets such as the Molecular Model Kits for Students.
- B.Ed. and teacher-training sessions on activity-based genetics teaching.
Standard Scope of Supply
The kit contains the specially shaped plastic base pieces, the sugar pieces and the central supporting spine needed to build the 12 base pair double helix, which measures 12 x 12 x 40 cm when finished. Extra kits for group work, or display DNA models, can be added to the quotation.
Packing, MOQ and Lead Time
You may ask for a price on one kit for demonstration or on enough kits for students to work in small groups. Science Lab Supplies replies with a quotation giving the packing, delivery time and price for that number of kits, and other biology lab equipment can be listed on it too.
Because Science Lab Supplies holds an Importer-Exporter Code, it is able to ship to buyers in Bangladesh, Zambia, Rwanda, South Africa, Qatar and Sri Lanka. Send your requirement through the contact page, build a list in the enquiry cart, or use the lab tender page for tender documents.
Frequently Asked Questions
How many base pairs does the kit build?
It builds a 12 base pair segment of DNA. Each base has a subtly different shape and the sugars are moulded in a slightly different plastic, so the completed model flexes into a double helix measuring 12 x 12 x 40 cm.
Can the helix be separated into single strands?
Yes. Move the central supporting spine and pull the helix apart along the hydrogen bonds, and it divides into two separate strands, which is useful for explaining how replication begins.
How is it different from the Deluxe kit?
The Deluxe kit uses unlabelled colours for the four bases so students design their own pairing code, and it is twisted into a helix instead of being built around a centre post. This kit uses a central supporting spine.
Where is the plastic assembly kit produced?
In India. Science Lab Supplies manufactures the kit at its Saha, Ambala site, and the same team prepares your quotation, packs the order and arranges dispatch.
