DNA Twist (1-08978-00)

DNA Twist is a learning tool designed for students or other individuals who are blind or have low vision disabilities. The model that demonstrates the structure of the DNA molecule in a way that is accessible to visually impaired students. The DNA Twist model is made of two foam sidebars representing the sugar-phosphate “backbone” and ten rungs representing the paired bases. The paired-base rungs are made of contrasting colors and textures to convey the base-pairing rules that govern the structure of double-stranded DNA molecules. The model is shipped flat and twists to form the double-helix configuration of a DNA molecule. The model holds its shape when twisted. The stand holds the model in its twisted formation, and a short instruction booklet provides information about DNA and educational resources.

Includes:

• DNA twist model
• Stand with a non-slip adhesive bottom (user applies)
