About the DNA Double Helix black outline icon
Two strands twist around each other in a double helix, joined by short parallel rungs and running diagonally across the frame. It stands for genetics, heredity and life science research. Use it in biotech sites, lab reports, medical and ancestry apps, science lesson slides or a health testing product page.
The helix makes about three turns, with rungs drawn only where the strands cross so the spiral stays readable. Line weight is uniform end to end. It pairs with microscope, test tube and molecule icons. At small sizes, crop to a single twist.
This is the black outline version of the dna double 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.
