DNA Double Helix Model with letter-labelled bases

This is a vivid, 3-dimensional DNA double-helix model, clearly colour-coded and letter-labelled to show the four nucleotide bases: adenine (A), guanine (G), cytosine (C), and thymine (T). The model comprises twelve base-pair rungs, allowing students to see exactly how A pairs with T and G pairs with C. It is mounted on a sturdy stand and designed to rotate freely around its central axis, so you can examine the helix from any angle.

Features

• Color-coded Bases: Each of the four nucleobases is marked with its letter (A, G, C, T) and a distinct colour for instant visual recognition.
• Twelve Base Pairs: Accurately represents one full turn of the DNA helix with 12 paired rungs.
• Rotatable Design: The helix spins smoothly on its supporting rod, making it easy to demonstrate strand orientation, major/minor grooves, and base-pair complementarity. 
• Stable Base: A weighted platform ensures the model remains upright during handling and rotation.

Dimensions: 13 × 13 × 40 (H) cm; 

Material: Durable plastic, metal rotating rod, and base.

   
This DNA model makes abstract molecular biology concepts tangible, giving learners a hands-on way to explore the structure and pairing rules that underlie genetics.
