This 12-layer model (one complete turn of the double helix) is designed for self-assembly, with the double helix structure becoming self-evident as the model is constructed. Components include colour coded bases (G,C,A and T), deoxyribose and phosphate groups, as well as a display stand. The model may be assembled on the stand for display, or laid flat for a demonstration of unzipping and replication. It is also possible to combine this DNA model with an RNA model (SRNA12) to explain transcription and protein synthesis. Approximately 24cm high.

Note: 22 layer model also available (AMDNA060-22)
