Orbit ProView DNA Model

Product Description

View the structure and composition of DNA: 12 base pairs show more than one turn of the double helix and major and minor groves. Every atom is shown, colour-coded, with the correct bonding angles. Pupils can make up the subassemblies in groups: Thymine-Adenine; Cytosine-Guanine, sugar rings and phosphate groups which can then be brought together to make the finished model. The 85cm model is suspended between two plates on clear strings which can be hung or supported by an display stand (not included). Includes comprehensive instructions and a worksheet examining the structure of DNA and the mechanism of transcription. Also available as a part or fully assembled model.
