Genetic DNA Helix black outline icon
Vertical DNA double helix with two twisting strands joined by short rungs
About the Genetic DNA Helix black outline icon
Two strands twist around each other down a tall vertical axis, crossing three times and joined by short horizontal rungs that stand for base pairs. It communicates heredity, genome research and molecular biology in a single mark. Use it on genetic testing services, biotech and pharma sites, lab report headers, science courseware and healthcare app sections on family history.
The strands thicken at the widest bulges and taper where they cross, which gives the helix a sense of depth without shading, and the rungs are spaced tighter near the center. It pairs with microscope, test tube and molecule icons in the library. Its tall proportion suits vertical cards better than wide banners.
This is the black outline version of the genetic dna helix icon: even, monoline strokes that stay crisp at small sizes and suit clean, minimal interfaces, wireframes and light backgrounds.
It downloads free as an SVG vector or transparent PNG in seven sizes, and the free online editor lets you recolor it, apply gold, silver, neon and gradient styles, add animation, or convert it to EPS, PDF and DXF.
