DNA Model Kit
Product Code : EL-ZM-10607
Quick answer: The DNA Model Kit is a construction kit for building a three-dimensional DNA double helix. Colour-coded bases snap together on a centre rod that represents hydrogen bonds, and two flexible strands stand for the alternating pentose and phosphate units. It is used to teach base pairing and DNA structure. Lab Exports manufactures it in Delhi for schools, colleges and universities.

How the kit is used in teaching
DNA is a double helix: two sugar-phosphate backbones run in opposite directions, and the bases on the inside pair by hydrogen bonding, adenine with thymine and guanine with cytosine. Because each base has only one partner, the sequence on one strand fixes the sequence on the other, which is the basis of replication and of the genetic code.
Building the helix by hand makes these rules concrete. Students choose colour-coded bases for a given sequence, snap each pair onto the centre rod, and finish with a helix that turns on its base for discussion.
- Sort the parts by colour and read the printed instruction manual.
- Write a short base sequence for one strand and select the complementary bases for the other.
- Snap each base pair together and attach it to the centre rod.
- Follow the manual to join the flexible strands and complete the double helix.
- Mount the finished helix on its base and rotate it while discussing base pairing and replication.

Frequently asked questions
What does the DNA model kit teach?
It teaches the base-pair sequence and function of DNA: students build the double helix with colour-coded bases, so the pairing rules and the two-strand structure become clear.
Does the DNA model rotate once assembled?
Yes. When assembled, the helix rotates on a sturdy base so it can be viewed from every side.
What is in the DNA Model Kit?
Materials to construct one model and a printed instruction manual.
