The Science of DNA Extraction
Key Steps:
- Breaking cells open: Soap dissolves cell membranes
- Releasing DNA: Salt helps separate DNA from proteins
- Precipitating DNA: Cold alcohol causes DNA to clump together
- Visualizing DNA: White strands at alcohol interface
Why It Works:
DNA is soluble in water but not in alcohol. When alcohol is added, DNA precipitates out of solution, becoming visible as white, stringy strands between the layers.
