Molymod Advanced Mini DNA 22‑Layer Kit – Double Helix Model with Major & Minor Grooves

This Molymod Advanced Mini DNA 22‑Layer Kit provides a highly detailed and accurate representation of the DNA double helix, now enhanced with clearly defined major and minor grooves for advanced structural study. Ideal for KS4, GCSE, A‑Level Biology, and introductory university courses, this kit allows students to explore base‑pairing, strand structure, and molecular arrangement through hands‑on construction.

The model includes 22 base pairs comprising the four nucleotides—Thymine (orange), Adenine (blue), Guanine (green), and Cytosine (yellow)—with fully colour‑coded deoxyribose sugars and phosphate groups. The assembled structure stands approximately 44cm high × 11cm diameter and is supported by a sturdy stand with twin support rods and spacers for alignment.

Supplied in a durable plastic storage box, this kit includes all necessary components and a clear assembly leaflet, making it perfect for classroom demonstrations, revision, and practical learning.
