DNA black filled icon
Outline DNA double helix drawn diagonally with paired cross rungs
About the DNA black filled icon
Two backbone strands twist around each other along a diagonal axis, joined by parallel rungs that represent base pairs, with the helix widening at the center and tapering at both open ends. It communicates genetics, heredity, molecular biology and biotech research. Use it on lab and diagnostics sites, DNA test kit pages, pharma decks, science courseware and health app sections about ancestry or genetic risk.
The diagonal placement fills a square frame edge to edge and the rung spacing tightens toward the twists, which reads as rotation without any shading. It pairs with microscope, molecule, test tube and lab flask icons. The fine rungs need room, so use 40 px or larger.
This is the solid black filled version of the dna icon: a bold silhouette that reads clearly at 16-24 px and on dark or busy backgrounds, and prints well in one colour.
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.
