A classic double-helix view with the sugar-phosphate backbone, paired bases, and 5' to 3' directionality labeled.
Close-up of adenine–thymine (2 hydrogen bonds) and guanine–cytosine (3 hydrogen bonds) base pairs, labeled.
A single nucleotide broken down into its three components: phosphate group, deoxyribose sugar, and nitrogenous base.
The "untwisted" ladder model of DNA with the backbone rails and base-pair rungs labeled, great for showing the 3D helix in 2D.
An unlabeled double helix with blank label lines pointing to key structures, ready for students to fill in.
A side-by-side comparison of DNA (double-stranded, deoxyribose, thymine) and RNA (single-stranded, ribose, uracil).
Use these when you need a DNA structure diagram quickly. Copy one prompt, paste it into the generator, then adjust the view, labels, or worksheet style.
A textbook-style DNA diagram with the main parts named.
Create a labeled DNA double helix diagram. Show the sugar-phosphate backbone on the outside, A-T and G-C base pairs in the middle, hydrogen bonds between bases, and 5' and 3' ends on both antiparallel strands. Use clean textbook labels with leader lines, white background.
Zoom in on A-T and G-C pairing rules.
Create a close-up DNA base-pairing diagram showing adenine paired with thymine using 2 hydrogen bonds and guanine paired with cytosine using 3 hydrogen bonds. Label each base by full name and abbreviation, label the hydrogen bonds, and color-code each base. White background.
Unlabeled version for student labeling practice.
Create a blank DNA double helix worksheet. Draw the double helix with visible backbone and base pairs, but leave empty callout lines for students to label sugar-phosphate backbone, base pair, hydrogen bond, nucleotide, and 5' and 3' ends. No filled-in labels. Black-and-white, printer-friendly, white background.
A side-by-side comparison for class notes.
Create a side-by-side comparison diagram of DNA and RNA. Show DNA as a double-stranded helix with deoxyribose and thymine, and RNA as a single strand with ribose and uracil. Label the number of strands, sugar type, and base difference. Clean colorful biology style, white background.
A DNA structure diagram is a scientific illustration that shows the molecular architecture of deoxyribonucleic acid. The most common view is the double helix, two antiparallel strands of alternating sugar and phosphate groups wound around each other, with nitrogenous base pairs (adenine–thymine and guanine–cytosine) stacking in the interior like rungs on a twisted ladder. Other important views include the single-nucleotide diagram (phosphate + deoxyribose + base), the ladder or "untwisted" model that makes the antiparallel arrangement clear, and close-up base-pairing diagrams that show hydrogen bonds. Figviz generates all of these views from a plain text description, so you can get a labeled, print-ready diagram in seconds without drawing software.
Always show the strands as antiparallel, label 5' at the top of one strand and 3' at the top of the other so the opposing directionality is visible. Keep base pairing correct: A pairs only with T, and G pairs only with C. In a helix diagram, the backbone belongs on the outside and the bases face inward. For the ladder model, stress the "untwisted" nature so viewers understand how the 3D helix maps to the 2D rungs. If you need a diagram for a comparison (DNA vs RNA), highlight deoxyribose vs ribose and thymine vs uracil as the two key chemical differences. For worksheet diagrams, use blank label lines rather than filled labels so students complete them, just mention "unlabeled with blank callout lines" in your prompt.
