DNA Activity Model
Product Code : LSK-HSM-10991
DNA Activity Model (SKU LSK-HSM-10991) is a construction set of 48 shaped bases, four strands and two supporting rods with pedestals, from which students build two complete DNA segments. Adenine, cytosine, guanine and thymine are shaped so that only the correct partners fit, which makes base pairing self-checking. It suits activity-based genetics teaching in school and college. Science Lab Supplies, a manufacturer at Plot 448, HSIIDC Industrial Area, Saha, Ambala, sells the set to schools, colleges and dealers.
Specifications
Below is the specification of the 48-base activity set. In short, it holds enough shaped bases and strands for two full DNA segments, two supporting rods on pedestals to hold them, and illustrated instructions, with an overall size of 12 x 12 x 46 cm.

Applications and Experiments for the DNA Activity Model
With the activity set, two groups of students can each build a complete DNA segment, finding for themselves that adenine fits only thymine and guanine fits only cytosine. The finished segments can then be compared side by side. It supports NCERT Class 12 Molecular Basis of Inheritance and B.Sc. genetics practicals.
- Class 12 biology: complementary base pairing and the double-stranded structure of DNA.
- Comparing two segments: showing how a change in base sequence changes the message carried.
- Gene-to-protein lessons: moving from the DNA segments to the PVC Protein Model.
- Inheritance topics: relating DNA to chromosomes on the Reproduction of Sexual Cells - Meiosis wall chart.
Standard Scope of Supply
One set contains 48 bases, four strands, two supporting rods with pedestals and illustrated instructions, enough to construct two complete DNA segments, with an overall size of 12 x 12 x 46 cm. Additional sets for larger classes, or other DNA models and biology charts, can be added to the quotation.
Packing, MOQ and Lead Time
A quotation can cover a single activity set or as many as your class groups need. Science Lab Supplies itemises the packing, delivery time and price for that quantity, and can add other school biology lab equipment from the same range so that the department receives one combined offer.
Science Lab Supplies is registered as an exporter under an Importer-Exporter Code and can ship to buyers in Rwanda, South Africa, Qatar, Sri Lanka, Vietnam and Malaysia. Message us on the contact page, put the sets into the enquiry cart, or follow the lab tender page for bid paperwork.
Frequently Asked Questions
How many DNA segments can students build with one set?
One set builds two complete DNA segments. It contains 48 bases, four strands and two supporting rods with pedestals, so two groups can work in parallel and then compare results.
How do students know they have paired the bases correctly?
The four bases are designed so only the proper partners fit together. A wrong pairing simply will not connect, so students can check their own work while they build.
Are instructions included?
Yes. Illustrated instructions come with the set, guiding students through attaching the bases to the strands and mounting the finished segments on the supporting rods and pedestals.
Does the quotation come from the manufacturer?
It does. Science Lab Supplies manufactures the DNA Activity Model in Saha, Ambala, India, and prices it itself, so there is no distributor layer between the factory and your school.
