What is the purpose of ethanol in a DNA extraction experiment?
We were doing a lab experiment in biology class in which we extracted DNA from a banana-detergent solution mixture.(The detergent solution was made of 100ml of detergent, 90ml of water, and 5g of salt.) We then added ethanol to the mixture. I know detergent breaks down the lipids in cells and salt takes away the moisture from cells but how does ethanol affect cells?
