DNA black outline icon
Outline icon of a DNA double helix on a diagonal with ladder rungs joining the two strands
About the DNA black outline 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 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.
