About the DNA Double Helix black filled 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 solid black filled version of the dna double helix icon: a bold silhouette that reads clearly at 16-24 px and on dark or busy backgrounds, and prints well in one colour.
