DNA black outline icon
DNA double helix drawn diagonally with short rungs linking the two twisted strands
About the DNA black outline icon
Two curved backbones twist around each other along a diagonal, joined by short parallel rungs that crowd together where the strands cross and open out at the wider turns. The shape stands for genetics, heredity, molecular biology and research. Use it in biotech websites, lab report headers, medical test result screens, science course material and health app sections.
The helix runs corner to corner with free ends that hook outward, so it fills a square frame on the diagonal. Pair it with microscope, molecule and test tube icons; rotate it upright if you need a narrower column, and keep it above 24 px so the rungs stay separate.
This is the black outline version of the dna icon: even, monoline strokes that stay crisp at small sizes and suit clean, minimal interfaces, wireframes and light backgrounds.
