Outline DNA double helix drawn diagonally with connecting rungs at its center
About the Genetic DNA Helix black outline icon
Two strands twist around each other along a diagonal axis, with short parallel rungs bridging them at the widest point of the helix and the ends tapering away to open tips. It communicates genetics, heredity, molecular biology and scientific research at a glance. Use it in biotech product pages, lab and clinical testing dashboards, ancestry or DNA-kit apps, medical presentations, and university course listings.
The corner-to-corner diagonal gives the mark more energy than an upright helix and fills a square frame evenly. Only the central turn carries base-pair rungs, which keeps the line count low and readable. It pairs well with microscope, test tube and molecule icons; at small sizes the rungs merge, so favor 32px and up.
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.
