This detailed model aids understanding of the chemistry and structure of DNA.
Building the DNA model engages and educates students. Groups can work together to make up the subassemblies – 15 Thymine-Adenine and Cytosine-Guanine base pairs, sugar rings and phosphate groups – which are joined together to make one and a half turns of the double helix and to show the major and minor grooves of the protein lysozyme.
Each atom is shown, colour-coded, with the correct bonding angle and coloured bonds indicate covalent or hydrogen bonding.
Constructed using the Minit molecular modelling system, the finished model is 1 metre high and 42 cms wide and can be suspended from a suitable hook.
Contents: 880 atoms and 1200 bonding straws, support plates for hanging the model plus assembly instructions and a worksheet.
Part and fully assembled versions are also available.
