Extract DNA from strawberries
A classic kitchen extraction: detergent breaks cell membranes, salt helps DNADNADouble-stranded molecule storing genetic information as A, T, G, C bases. clump, and alcohol (usually chilled) makes DNADNADouble-stranded molecule storing genetic information as A, T, G, C bases. precipitate as visible white strands.
Materials
- Fruit tissue
Ripe strawberries are soft and DNADNADouble-stranded molecule storing genetic information as A, T, G, C bases.-rich, so the precipitate is easy to see.
- Detergent and salt
Detergent dissolves membranes; salt helps DNADNADouble-stranded molecule storing genetic information as A, T, G, C bases. aggregate.
- Mashing bag
Mechanical disruption releases cell contents.
- Coffee filter
Filtration removes debris while DNADNADouble-stranded molecule storing genetic information as A, T, G, C bases. stays in the liquid.
- Cold alcohol
Alcohol precipitates DNADNADouble-stranded molecule storing genetic information as A, T, G, C bases. at the interface; kitchen protocols usually chill it first as a practical convention.
Tip: use your phone as a lab-bench companion — one step at a time.
