Description

General description

An extensive model system offering 15 atomic bonding configurations in 12 colors of plastic atoms. The carbon atom is represented in nine configurations: linear, trigonal (in five angle variations), tetrahedral, octahedral, trigonal-bipyramidal. Models come in two sizes: Orbit and Minit. Spare atom centers and bonding tubes are available for all model kits.

Please see Technical Information Bulletin AL-183 for a listing of these items, available on our website at sigma-aldrich.com

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.
