Highly accurate model of DNA structure.

• Paint and construst a DNA model
• Precision fitted parts
• Snap together construction

Students construct this DNA model from six different molecular pieces, collectively depicting sixteen nucleotide pairs worth of DNA (8 AT and 8 GC pairs). The base pairs and the sugar and phosphate units are each manufactured as single plastic 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 may be disassembled and reassembled like a puzzle, enabling extended use. The model is unpainted and individual molecules may be painted by students either prior to or after assembly. Model with paint includes six paint colors, paint thinner, and six brushes. A laboratory exercise and problem set accompany the model. After completing the building exercise and problem set, students will have a better understanding of the double helical structure and the function and properties of DNA.
