DNA black outline icon
DNA icon of a diagonal double helix strand with rungs
About the DNA black outline 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 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.
