DNA Diagram Generator

Prompt

Create a fully labeled DNA double helix on a white background, drawn vertically as a right-handed spiral that twists clockwise as it recedes from the viewer. Draw the two sugar-phosphate backbones as ribbons on the outside, alternating pentagon deoxyribose sugars with circular phosphate groups, and point every base inward so the pairs meet in the middle. Colour adenine, thymine, guanine, and cytosine differently and pair A with T using two short hydrogen bond dashes and G with C using three. Label "Sugar-phosphate backbone", "Deoxyribose", "Phosphate group", "Hydrogen bonds", "Base pair", and each base by name. Mark 5′ and 3′ at opposite ends of each strand with small arrows showing they run antiparallel. Thin dark leader lines, readable sans-serif text.

Prompt

Create a blank DNA worksheet. Draw the same right-handed double helix with backbones on the outside and paired bases meeting in the middle, in clean line art with pale uniform fills and no text anywhere on the figure. Keep the pairing structurally correct — two hydrogen bonds on one pair type and three on the other — but leave every base unlettered. Draw thin leader lines from each part out to a short horizontal ruled blank line, numbered 1 to 8. Add a word bank box below reading "double helix, sugar-phosphate backbone, deoxyribose, phosphate group, nitrogenous base, hydrogen bond, base pair, nucleotide". Generous white space, no answer key.

Prompt

Create a simple, easy-to-draw DNA diagram for younger students, styled as a twisted ladder. Draw two thick dark uprights spiralling gently to the right in a single flat colour, joined by straight rungs. Split every rung in the middle and colour the halves so that blue always faces orange and green always faces purple, with the letters A, T, G, and C printed large on the rungs and A always opposite T, G always opposite C. Label only three things in big readable text: "Sugar-phosphate backbone", "Base pair", and "Double helix". Bold flat colours, plenty of white space, no hydrogen bond detail.

Prompt

Create a base pairing rules diagram on a white background, drawn as a flat untwisted ladder so the chemistry is clear. Show two stacked panels. The top panel pairs adenine with thymine, joined by exactly TWO dashed hydrogen bonds, captioned "A = T, two hydrogen bonds". The bottom panel pairs guanine with cytosine, joined by exactly THREE dashed hydrogen bonds, captioned "G ≡ C, three hydrogen bonds". Draw adenine and guanine as two fused rings labeled "Purine (two rings)" and thymine and cytosine as single rings labeled "Pyrimidine (one ring)". Add a caption reading "A purine always pairs with a pyrimidine, so the helix stays the same width". Show no uracil anywhere.

Prompt

Create a labeled diagram of a single DNA nucleotide on a white background. Show the three parts separately along the top — a circular "Phosphate group", a pentagon "Deoxyribose sugar", and a rounded "Nitrogenous base" — then show them joined below into one nucleotide with arrows from each part to its place in the assembled unit. Add a caption reading "Every nucleotide has exactly three parts". Beside it, draw three nucleotides linked into a short strand so the phosphate of one connects to the sugar of the next, labeled "Sugar-phosphate backbone", with the bases projecting sideways labeled "Bases point inward to pair". Note that the base can be adenine, thymine, guanine, or cytosine.

Prompt

Create a labeled DNA replication diagram on a white background. Draw the parent double helix at the left opening into a Y-shaped replication fork, with "Helicase" labeled at the fork unzipping the two strands by breaking the hydrogen bonds. Label "DNA polymerase" building each new strand by adding free nucleotides, keeping A opposite T and G opposite C on every rung. At the right, show two complete daughter molecules, each drawn with one dark original strand and one bright new strand, captioned "Semi-conservative: each new molecule keeps one original strand". Label "Parent strand", "New strand", and "Free nucleotides", and mark the 5′ and 3′ ends on the fork.
