Molecular Model – Orbit Small DNA (DNA & RNA Structure Model) [0505]

The Orbit Small DNA Molecular Model is a clear and engaging three‑dimensional teaching aid designed to help students understand the structure of DNA. Suitable for KS3 and above, this compact model provides an accessible introduction to molecular biology while remaining detailed enough to support more advanced study.

The model represents a section of the DNA double helix that is six base pairs high, clearly showing how the two strands are held together by complementary base pairing. Its design also allows it to be used to demonstrate RNA strands, making it a versatile resource for exploring similarities and differences between DNA and RNA.

With an overall size of approximately 25cm in height and 10cm in width, the model is large enough for effective classroom demonstration while remaining easy to handle and store. As part of the Orbit molecular model range, it is robust, colour‑coded, and designed for repeated use in busy educational environments.

Key Features
