Strawberry DNA extraction with 7th grade

The 7th grade mashed some strawberries and extracted DNA.

Strawberry juice was mixed with salt water soap. The mixture was strained into a clean cup. Ice cold isopropyl alcohol was carefully added to the mixture to separate the DNA from the other substances in the mixture. 

The white string-like substance is DNA. 


The girls collected the DNA from the mixture.
 

This is DNA under the microscope at magnification 10X.
