Orbit DNA-RNA Kit

The Orbit molecular model aids understanding of the process of DNA-RNA transcription.

The model shows 12 base pairs with each base (guanine, cytosine, thymine, adenine and uracil) in a different colour and the sugar rings, phosphate groups and hydrogen bonds in black, red and white respectively. Sufficient base pairings are included to show one turn of the double helix.

The strands of DNA can be joined and taken apart to demonstrate the transcription of RNA.
