What it is
Summary
AI-generated from vendor-published content · May 23, 2026
This is a tactile three-dimensional model of the DNA double helix structure, designed so students with low vision or blindness can explore molecular biology concepts through touch rather than diagrams. Science curricula heavily rely on visual representations of DNA — this gives students who can't access those diagrams a physical way to understand base pairing, the sugar-phosphate backbone, and the helical twist. It's a complete, standalone teaching tool — no assembly or additional equipment required. Federal Quota eligibility means it can be funded through state education quota accounts for eligible blind students, which is worth checking with your TVI before purchasing out of pocket.
