This file contains the DNA model which is constructed using icospheres that accurately portray how the elements are set up (Phosphorous, Nitrogen, Carbon, and Hydrogen)  Along with the DNA model, the file contains the separate base pairs (A G T C)  and a model of a single helix strands its own object.  The DNA is composed of a repeating strand of Adenine and Cytosine base pairs.  This model has value for commercial use and because of the accurate base pairing, it has educational values well.
