DNA Structure Model, Plastic Assembly Kit
Product Code : EL-HSM-10487
Quick answer: The DNA Structure Model, Plastic Assembly Kit is an easy-to-assemble kit that builds a 12 base pair DNA double helix from shaped, brightly coloured plastic pieces. It is used for hands-on lessons on DNA structure and on how the two strands separate along their hydrogen bonds. The assembled model measures 12 x 12 x 40 cm. Lab Exports manufactures it in Delhi for schools, colleges and universities.

How the kit is used in class
Building DNA by hand makes its rules concrete. In each base pair, adenine links to thymine by two hydrogen bonds and guanine links to cytosine by three, and the order of the pairs along the molecule carries the genetic code. In this kit each base has a subtly different shape, and the pieces flex so that the finished chain takes on the twist of a real double helix.
- Sort the plastic pieces by shape and colour, picking out the sugars and the four bases.
- Pair each base with its complementary partner and connect the pairs to the sugars of the two strands.
- Assemble all 12 base pairs; the shaped pieces flex so the chain forms a double helix.
- To demonstrate strand separation, move the central supporting spine and pull the strands apart along the hydrogen bonds.
Pulling the strands apart is a natural starting point for discussing replication and transcription, since both processes begin when the hydrogen bonds between base pairs are broken.

Frequently asked questions
How many base pairs does the DNA assembly kit build?
It builds a 12 base pair segment of the double helix.
Can the strands be separated after assembly?
Yes. Moving the central supporting spine allows the two strands to be pulled apart along the hydrogen bonds.
How is it different from the Deluxe kit?
The Deluxe kit (EL-HSM-10488) uses unlabelled base colours so students set their own pair coding, and it twists into a helix without a centre post.
