DNA Double Helix Model – 12 Segments, miniDNA® Kit

DNA double helix model kit illustrating base pairing, hydrogen bonding, and helical structure.

This hands-on molecular model kit represents a right-handed DNA double helix and is designed to help students clearly understand DNA structure and replication. With colour-coded components and accurate structural details, it supports visual learning of complementary base pairing, hydrogen bonds, and the spatial arrangement of the double helix. Ideal for classroom demonstrations, group activities, and senior biology study, the model can be assembled and disassembled to actively explore key genetics concepts.

Key Features

• Buildable DNA double helix model with 12 base-pair segments
