The model shows the five bases in red, green, blue, grey and white, the sugar rings in black and the phosphate groups in red. Yellow tubes join the sugar and phosphate groups. White pieces show the hydrogen bonding between the bases. The separate pieces can be joined and unjoined so you can demonstrate the transcription of RNA.

- 25 phosphoric acid units
- 50 nucleotide connectors
- Support stand, instructions and RNA transcription activity

Deoxyribonucleic acid (DNA) is a nucleic acid that contains the genetic instructions used in the development and functioning of all known living organisms and some viruses. The main role of DNA molecules is the long-term storage of information. DNA is often compared to a set of blueprints or a recipe, or a code, since it contains the instructions needed to construct other components of cells, such as proteins and RNA molecules. The DNA segments that carry this genetic information are called genes, but other DNA sequences have structural purposes, or are involved in regulating the use of this genetic information.
