DNA Twist is a 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.
Note: The APH Tactile Graphic Image Library (TGIL) has a file which allows you to print the DNA Twist on your own 3-D printer, according to its ability. Sign in or register for a free account at: https://imagelibrary.aph.org/aphb/.
