About the DNA Double Helix color outline icon
This icon shows a classic DNA double helix with two twisting strands connected by horizontal rungs, forming the familiar ladder-like structure. It represents genetics, heredity, molecular biology and biotechnology. Use it in science education materials, healthcare apps, research websites, lab reports and genetic-testing product pages.
The strands curve smoothly into an hourglass twist with evenly spaced connecting rungs, giving a clean and recognizable silhouette. It pairs well with microscope and lab-flask icons in science sets. Keep it at a reasonable size so the individual rungs remain distinguishable.
This is the colour outline version of the dna double helix icon: the same line drawing in an accent colour, useful for highlighting a state, a category or a brand tone without adding visual weight.
