The model is constructed from only six different molecular parts and depicts 16 nucleotide pairís worth of DNA (8 AT 8 GC pairs). The base pairs are manufactured in a single plastic piece as are the sugar and phosphate units. Because there are only nine molecular parts per nucleotide pair which snap together by means of a pop-it bead mechanism, the model can be easily assembled. The model is unpainted and may be painted by students in a 5-6 hour period.
A laboratory exercise and problem set accompany the model. After completing the laboratory exercise and problem set, students will have a better understanding of the aspects of the structure, function, and properties of DNA.
