You can see DNA without a microscope by extracting it and making it visible as a cloudy substance.
The process, based on the referenced YouTube video, involves making DNA visible as a precipitate. Here's how:
- You'll need a source of DNA (e.g., your own cheek cells obtained by rinsing your mouth).
- Mix the sample with water.
- Carefully pour cold isopropyl alcohol on top of the water mixture. The DNA, which is not soluble in alcohol, will precipitate out and become visible as a cloudy, white substance between the water and alcohol layers. The reference calls it "gunk" that appears between the two layers.
Essentially, the DNA separates from the solution and clumps together, making it visible to the naked eye. This is not visualizing the double helix structure, but rather seeing a mass of extracted DNA.
