Genetic DNA Helix black filled icon
Vertical DNA double helix with two twisting strands joined by short rungs
About the Genetic DNA Helix black filled icon
Two strands twist around each other down a tall vertical axis, crossing three times and joined by short horizontal rungs that stand for base pairs. It communicates heredity, genome research and molecular biology in a single mark. Use it on genetic testing services, biotech and pharma sites, lab report headers, science courseware and healthcare app sections on family history.
The strands thicken at the widest bulges and taper where they cross, which gives the helix a sense of depth without shading, and the rungs are spaced tighter near the center. It pairs with microscope, test tube and molecule icons in the library. Its tall proportion suits vertical cards better than wide banners.
This is the solid black filled version of the genetic dna helix icon: a bold silhouette that reads clearly at 16-24 px and on dark or busy backgrounds, and prints well in one colour.
