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
  • Finished model is 85 x 40cm (h x w) and is suspended between two plates on clear strings which can be hung or supported by an display stand (not included)
  • 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
