Extracting DNA From A Banana
This lab simulation walks through a classic DNA extraction: mixing salt and dish soap into warm water, mashing a banana, blending it with the extraction solution, filtering out solids, and layering cold ethanol on top of the filtrate to precipitate visible DNA strands. Each step is labeled clearly, showing how simple household chemicals break down cell membranes and separate genetic material. Useful for middle and high school biology or chemistry students learning basic lab technique and cell structure.

The prompt that made it
Create a professional educational 3D chemistry and biology laboratory simulation on a completely clean white background. Scene 1 — Preparing the Extraction Solution: Show 100 mL of warm water in a transparent laboratory beaker. Add one tablespoon of table salt (NaCl) and one tablespoon of liquid dish soap. Stir the mixture thoroughly with a glass stirring rod until the ingredients are well mixed. Show clear labels: “100 mL Warm Water”, “Salt — NaCl”, and “Dish Soap”. Scene 2 — Preparing the Banana: Show one fresh banana placed inside a clean transparent plastic bag. Mash the banana thoroughly by pressing and crushing it until it becomes a smooth, finely mashed mixture with no large pieces. Scene 3 — Mixing: Pour the prepared warm water, salt, and dish soap solution into the bag containing the mashed banana. Mix the contents gently and thoroughly. Show the banana mixture becoming well combined with the extraction solution. Leave the mixture undisturbed for approximately 3 minutes. Scene 4 — Filtration: Pour the banana mixture through a clean laboratory strainer or fine filter into a second transparent laboratory container. Clearly show the larger banana solids being trapped by the strainer while the liquid filtrate passes through into the container. Scene 5 — Adding Ethanol: Transfer the filtered banana extract into a clean transparent test tube or narrow laboratory container. Carefully add cold ethanol (ethyl alcohol, C₂H₅OH) slowly along the side of the container so that it forms a separate upper layer above the banana extract. Do not show the ethanol being mixed vigorously with the extract. Scene 6 — DNA Precipitation: Show the mixture resting for several minutes. Gradually reveal a cloudy, whitish, stringy material forming at the boundary between the ethanol and banana extract and rising into the upper ethanol layer. This represents precipitated banana DNA. Final Scene: Show a close-up macro view of the cloudy white DNA strands floating in the upper ethanol layer. Make the DNA appearance realistic and scientifically appropriate, with fine white translucent string-like material clearly visible against the clean white laboratory background. Scientific Explanation: The salt and detergent help release cellular material, while ethanol causes DNA to precipitate and become visible as a cloudy, whitish, string-like substance. Visual Style: Ultra-realistic educational 3D laboratory simulation, accurate scientific glassware, realistic liquids and textures, smooth camera movements, clean white background, soft studio lighting, high detail, professional biology experiment presentation, no people, no cartoon style, no explosions, no unrealistic effects. Add clear labels: “Banana” “Warm Water — 100 mL” “Salt — NaCl” “Dish Soap” “Mashed Banana” “Filtration” “Ethanol — C₂H₅OH” “Precipitated DNA”
