DNA black filled icon
DNA icon of a diagonal double helix strand with rungs
About the DNA black filled icon
Two intertwined strands twist diagonally across the frame, joined by short diagonal rung bars, and the ends splay apart into loose parallel lines rather than closing neatly. It represents genetics, heredity and biotechnology, fitting science dashboards, medical apps, research presentations, lab reports and biotech branding.
The diagonal tilt gives it more motion than a typical vertical helix, and the alternating solid rungs add rhythm without clutter. It pairs with molecule and biology icons in the library. Rotate it upright if it needs to align with a vertical list of body text.
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.
