Build 3D DNA models of the helix, replication, and transcription

Ask for a double helix or a replication fork in any chat, or open your genetics chapter as a PDF. You get a labeled model with the strands and enzymes named, ready to rotate and zoom in the chat message or on its own page.

Quick answer

Can AI make a 3D model of DNA?

Updated October 2026 · 3D models are in Beta

Yes, as a teaching model. Ask in any chat for the double helix, a replication fork, or RNA polymerase at work, or open your genetics PDF, and Scholarly's AI writes a labeled model with base pairs, strands, and enzymes named. It can animate a process if you ask. Sequence and spacing are illustrative: it doesn't read sequence files or use experimental coordinates, so use it to explain how the process works.

DNA is easy to draw and hard to picture working. A ladder in a textbook doesn't show the twist, the major and minor grooves, or the fact that the strands run in opposite directions. That last part is why the lagging strand gets built in Okazaki fragments, and a replication fork makes more sense when you can turn it and see both strands at once.

Follow the process, not just the structure. Ask for helicase opening the strands while primase and DNA polymerase work behind it, RNA polymerase reading a template strand, or a ribosome matching tRNAs to codons. To match your course, build from the chapter as a PDF and view the model on its own page. A chat model has no source PDF, so tell it the terms you want.

Know what it isn't. Scholarly doesn't read FASTA, GenBank, PDB, or CIF files, doesn't use experimental coordinates, and doesn't compute anything from a sequence, so the bases you see aren't your gene. Don't use a model for primer or guide design, variant interpretation, diagnosis, or clinical decisions. Use SnapGene or Benchling for sequence work, and PyMOL or ChimeraX for real nucleic acid structures.

How it works

How to build a DNA model

Choose a structure or a process, name the players, and confirm.

  1. 01

    Ask in chat or open your chapter

    Ask in any chat while you're reading, or start a 3D model from a genetics chapter or lecture handout saved as a PDF.

  2. 02

    Name the structure or process

    The double helix, replication, transcription, or translation, plus the enzymes and strands to label. Confirm the build, which uses 1 AI Creation Credit.

  3. 03

    The AI builds and animates

    Over a few minutes it writes the model in three.js, with colored bases, labels, and motion if you asked for it.

  4. 04

    Watch it from any side

    Rotate and zoom in the message, or open it full page. Change a base's color or reword a label by asking, and export on a paid plan.

Use cases

Where DNA models help

Anywhere the order of events, or which strand is which, is the hard part.

Intro biology and genetics

Base pairing, the sugar-phosphate backbone, and how the helix twists.

Molecular biology

The replication fork: helicase, primase, DNA polymerase, ligase, and Okazaki fragments.

Gene expression

Transcription, splicing out introns, and translation at the ribosome.

Chromatin and regulation

DNA wrapped around histones into nucleosomes, or a transcription factor at a promoter.

Biotech onboarding

CRISPR-Cas9 with its guide RNA, explained to a new hire or a non-specialist.

MCAT and Step 1 review

The enzymes and steps you need to recall, labeled from your own review material.

Try asking

DNA and RNA requests to try

Name the structure or process, then the parts to label.

  • Build a DNA double helix and label the base pairs, the sugar-phosphate backbone, and the major and minor grooves.

  • Show a replication fork with helicase, primase, DNA polymerase, and the leading and lagging strands labeled.

  • Animate RNA polymerase moving along a template strand and making mRNA.

  • Show DNA next to RNA and label what's different: uracil, ribose, and a single strand.

  • Model a ribosome reading an mRNA, with tRNAs in the A, P, and E sites.

  • Wrap DNA around histones to show a nucleosome, and give the histones their own color.

Beta

What it can and can't do today

3D models are in Beta. For DNA and RNA, that means illustrative teaching models, not real sequences or solved structures.

Works today

  • Double helix, RNA, and chromatin models with base pairs, strands, and grooves labeled.
  • Process models of replication, transcription, and translation, animated if you ask in the build.
  • Builds in any chat and appears in the message, or builds from one genetics PDF on its own page.
  • On paid plans, export a 4K PNG, a transparent PNG, an 8-second 1080p turntable MP4, or a .glb file.

Not supported

  • Not CAD-accurate or engineering-grade. Models explain how something works; they are not measured designs.
  • No STL or OBJ export, and no 3D printing. Exports are images, a turntable video, and a .glb file.
  • No manual 3D editing tools: no sculpting and no dragging parts. You change a model by asking chat.
  • A model starts from one PDF or from an empty chat. For notes or slides, save them as a PDF, or describe the content in chat.
  • It's a Beta: preview every draft before you apply it, and check the labels before a model goes in front of a team.

FAQ

Frequently asked questions

Can I give it a real sequence?

You can mention one, but don't expect the model to be faithful to it. It doesn't read FASTA or GenBank files, and nothing checks it base by base. Keep real sequence work in SnapGene or Benchling.

Is the helix geometry correct?

It's illustrative. The AI aims for the familiar right-handed shape and can label the grooves, but it doesn't use experimental coordinates, so don't measure rise, pitch, or groove width from a model.

Can it animate replication or transcription?

Yes, if you ask in the build. Movement is written to explain the order of events, not to model real speeds or kinetics. Adding animation to an existing model counts as a new build, and changing an animation's speed is a small edit.

Can it show RNA as well as DNA?

Yes. Ask for mRNA, a tRNA cloverleaf, a hairpin, or a ribosome at work. Folded RNA shapes are illustrative, since it doesn't compute secondary or tertiary structure.

Can I use it to explain gene editing or a variant?

To teach the idea, yes: for example, Cas9 cutting at a guide RNA's target. It can't tell you what a real variant does, and it isn't for variant interpretation, diagnosis, or clinical decisions.

What does a DNA model cost?

A full build uses 1 AI Creation Credit, and you confirm it before it starts. Rewording a label or changing a color doesn't use a credit, while adding a new enzyme or a new step counts as another build. Exports need a paid plan.
