DNA black filled icon
Outline icon of a DNA double helix on a diagonal with ladder rungs joining the two strands
About the DNA black filled icon
Two strands twisting around each other on a diagonal axis, joined across the widest turn by a ladder of parallel rungs that represent base pairs. It stands for genetics, heredity and life science research. Use it in biotech and pharma websites, laboratory and test-result dashboards, medical or ancestry apps, science education material, and slides about innovation and genetic data.
The corner-to-corner diagonal gives the helix a long reading line, and the rungs are concentrated in the central bulge while the ends taper to bare curves, which keeps the silhouette light. It pairs with microscope, molecule and test tube icons. Rotate it upright if you need a narrow vertical slot.
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.
