DNA to structure
Free, no sign-up. It runs in your browser on Athanor’s own engine, and your structures never leave your device.
How to do it
Type or paste the bases, 5′ to 3′.
Choose DNA or RNA, and a single or double strand.
Copy the SMILES, or download a MOL file or an SVG.
How it works
Athanor builds the strand nucleotide by nucleotide, with every sugar, base and phosphate drawn as atoms and bonds, and lays it out the way a biochemistry text draws one. The formula and molar mass are those of the whole strand. It runs on Athanor’s own engine in your browser.
Strands up to 59 bases draw as a full structure. In the Athanor app, longer strands are drawn as beads you can expand.
