A
high quality model that combines powerful magnets with accurate
3-dimensional nucleotides to produce a 12-layer segment of DNA. Each
nucleotide separates into its three components – the nitrogenous base,
deoxyribose group and phosphate group – with each atom being colour coded to
assist identification. The magnets simulate the hydrogen bonds between
complimentary base pairs (G-C and A-T), and the phosphodiester bonds between
the phosphate group of one nucleotide and the deoxyribose group of another.
When not being used for instruction, the model can be displayed on its stand
or by hanging.

“By using the
Discovery Approach with the DNA Discovery Kit, your students can
encounter science as a dynamic, creative process. Armed with the bases,
deoxyribose groups and phosphate groups, and the same facts Watson and Crick
had in 1953, your students will be able to discover the structure of DNA for
themselves. In doing so, they will construct an understanding of DNA that
will allow them to build on their knowledge as they encounter more
sophisticated topics. They will also understand how this structure is
ideally suited to encode information that can be faithfully replicated.”
