This detailed and large-scale 3d model helps pupils to understand the chemistry, composition and structure of DNA. Building the double helix model engages and educates students. A great whole-class project, pupils work together to make up the subassemblies – the Thymine-Adenine and Cytosine-Guanine base pairs, sugar rings and phosphate groups – which are joined together to make an impressive display and teaching resource.

12 base pairs show more than one turn of the double helix and the major and minor grooves of the protein lysozyme. Each atom is shown and coloured bonds indicate covalent or hydrogen bonding. The finished model is 85cm high and 40cm wide and is suspended between two plates on clear strings which can be hung or supported by an display stand (not included). The kit contains 750 atoms and 850 bonding straws from the Orbit molecular modelling system, a set of wooden plates for hanging the model plus assembly instructions and a worksheet examining the structure of DNA and process of transcription.
