Dna

The dna icon represents the double helix structure of deoxyribonucleic acid, a fundamental molecule in genetics and biology. It is often used to symbolize genetic information, heredity, or scientific research.

In software or platforms focused on genetics, biology, or scientific research, this icon may appear as a logo or visual element. It can also be used in educational materials to represent the field of genetics.

From a UX perspective, this icon communicates a connection to scientific or genetic concepts, helping users understand the context or topic of a particular section or feature.

Dna is one of 1,500 icons in Sharp free icons, made by Streamline and released under CC BY 4.0. It is drawn on a 24 × 24 grid with a 1.5 stroke.

Sign in (it's free), then open Get icon, Install with shadcn CLI, and pick your package manager to copy the command. It adds DnaIcon to components/icons/streamline-sharp-dna.tsx: one file, a size prop (24 by default) and every SVG prop, with no icon package.

Copy it as React (from Get icon, or the Code section): a typed DnaIcon component you paste into your project, with no package to install. Only the icons you import reach your bundle. It works in Next.js and any React app.

Open Get icon, then Copy as code, and pick Vue, Svelte, Angular, Solid or Preact; the Code section shows each one too. Every version is one self-contained component with the SVG inside, and SVG and data URL copies are there for plain HTML and CSS.

With Pro, the shadcn.io MCP server lets Claude Code, Cursor or any MCP client find the Dna icon, or any of 1,500 Sharp free icons icons, and install it from a prompt.

It's drawn in currentColor, so it takes the text color wherever you use it: a class like text-primary recolors it. To bake a color in, set one in Customize before you copy.

Set width and height on the component, or a class like size-6. It's drawn on a 24 × 24 grid, so it stays sharp at any size. Customize also sets the size it exports at, its padding and rotation, and its stroke.

Dna is a line icon drawn with a stroke width of 1.5. Change it in Customize before you copy, or pass strokeWidth to the installed component when all of its strokes share one width.

Yes. It follows the text color, so with text-foreground (or any theme token) it changes with your light and dark themes. The icon is a vector, so it needs no separate dark asset.

Next to a visible label it's decoration: add aria-hidden="true" so screen readers skip it. Standing alone, as in an icon button, give the button a name instead, like aria-label="Dna", so screen readers say what it does.

Yes. DnaIcon passes every SVG prop to the svg element, so <DnaIcon aria-hidden="true" /> works, and so do role="img" with aria-label, or a title child, when it carries meaning on its own.

Yes. Open Get icon, then Download file: SVG for code or design tools like Figma; PNG, WebP or JPEG at 512px; or an ICO favicon with 16, 32 and 48px inside. Each one uses what you set in Customize.

Yes, with credit: CC BY 4.0 asks you to credit the author (Streamline) where you use the icons. The full terms are in the license, linked on this page.
