Use this cost-effective set to create an impressive display and teaching model. The built Minit Proview model shows the DNA double helix with up to 15 base pair layers and illustrates more than one turn of the double helix. Every atom is shown, colour-coded, with the correct bonding angles.

Groups can make up the subassemblies: Thymine-Adenine; Cytosine-Guanine, sugar rings and phosphate groups which can then be brought together to make the finished model. The model hangs between two plates from clear strings and comes with comprehensive instructions and a worksheet examining the structure of DNA and the mechanism of transcription.

Scale: 2 cm = 0.1 nanometer (1 A), Minit.
