Biological DNA Structure Teaching Model

Description

The Biological DNA Structure Teaching Model, also known as a DNA double helix model, is designed for biology, genetics and molecular biology teaching in laboratory and educational settings. This model allows students to assemble the DNA structure and then twist it into a double helix, helping demonstrate the three-dimensional arrangement of DNA in a practical classroom format. Unlike models that are built directly around a centre post, this model can be assembled and then formed into the double helix shape, supporting a more hands-on learning activity. Each of the four nitrogenous bases is supplied in a different unlabelled colour, allowing students to design their own base pair coding and explore DNA structure through supervised classroom discussion.

The model is removable from the plastic base and can be extended to its full length, making it useful for demonstrating strand separation and helping explain how DNA strands can separate during biological processes. The listed size is 23 × 22 × 68 cm, providing a large visual teaching format suitable for classroom demonstration, bench display and student observation. The listed weight is 1.4 kg, giving the model a practical size and weight for repeated educational handling, setup and storage.

This DNA model is suitable for school science laboratories, biology classrooms, university teaching laboratories and general educational environments requiring visual aids for genetics and molecular biology instruction. Teachers can use the model alongside diagrams, worksheets, textbook content or digital resources to support lessons on DNA structure, base pairing, double helix formation, genetic coding and strand separation. Users should assemble and handle the model carefully according to the supplied instructions. Components should not be forced during assembly or twisting, as this may damage connection points or model parts.

This product is intended for laboratory or educational settings only and should be used under appropriate teacher or laboratory supervision. This item is supplied as the biological DNA structure teaching model with plastic base only. Charts, worksheets, storage case and additional teaching accessories are not included unless specified separately.
