Diagonal DNA double helix with two twisting strands joined by short rungs
About the DNA Double Helix black outline icon
Two strands twist around each other in a double helix running diagonally across the frame, joined in the middle by short parallel rungs that represent base pairs. It signals genetics, heredity and life science research. Use it on biotech sites, lab reports, medical apps, ancestry test pages, science courseware and health startup branding.
The rungs appear only where the strands cross in the center, which keeps the ends light and the middle dense, a good use of contrast. The diagonal fills a square frame neatly. It pairs with microscope, molecule and test tube icons; 32 px keeps the rungs distinct.
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.
