DNA Model, Pre-Assembled, 1 Each

The DNA Model, Pre-Assembled by United Scientific is a classroom double-helix model built to a scale of 10 cm to 1 nm, depicting a 16 base pair section of DNA. Custom plastic moldings show the backbone and four bases in scale, and the 24 in model rotates on a central pillar and circular stand. Biology teachers use it to demonstrate DNA structure and base pairing.
