Understand DNA/RNA structure.

• Available as a single kit, or a class pack of 12
• Small kits can be combined to form larger sequences

This Orbit molecular model aids understanding of the process of DNA/RNA transcription.

The model shows six base pairs with each base (guanine, cytosine, thymine, adenine, and uracil) in a different color and the sugar rings, phosphate groups, and hydrogen bonds in black, red, and white respectively. The Class pack can also be combined for a series of 72 base pairs.

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