About the DNA color outline icon
A vertical double helix sits at the center of a thin circular frame. Two strands cross three times and the middle section is filled with short horizontal rungs that stand in for base pairs, while the top and bottom ends taper into open forks. The mark reads as genetics, heredity, molecular biology and DNA testing at a glance. Use it in lab software, health and ancestry apps, biotech presentations, research posters and medical record sections.
The helix is narrow relative to the enclosing circle, leaving generous breathing room so the shape stays crisp as a badge or avatar. Rung spacing is even and the strand weight matches the frame. Pair it with microscope, molecule and test tube icons; below 32 px the base-pair lines merge, so use a rung-free variant there.
This is the colour outline version of the dna icon: the same line drawing in an accent colour, useful for highlighting a state, a category or a brand tone without adding visual weight.
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.
