How does salt soap and ethanol extract DNA?
Salt soap helps break down cell membranes, releasing DNA from cells. Ethanol is added to DNA-containing solution to precipitate DNA out of solution, as DNA is not soluble in ethanol. The DNA can then be collected by spooling or centrifugation.
How can one extract DNA from a strawberry?
To extract DNA from a strawberry, you can mash the strawberry, mix it with a salt solution to break down the cell walls, filter out the solid parts, add alcohol to separate the DNA, and then carefully collect the DNA strands using a small stick or pipette.
How can one extract DNA from fruit?
To extract DNA from fruit, you can mash the fruit to release its juices, mix it with a salt solution to break down cell membranes, filter out solid particles, add alcohol to separate DNA from other molecules, and then collect the DNA strands that form at the alcohol layer.
What role does salt play in the process of DNA extraction?
Salt plays a crucial role in DNA extraction by helping to separate the DNA from other molecules in the cell. When salt is added to the mixture, it helps to neutralize the charges on the DNA and other molecules, allowing the DNA to clump together and separate from the rest of the cell components. This makes it easier to isolate and extract the DNA for further analysis.
How can one extract DNA from a fruit?
To extract DNA from a fruit, you can mash the fruit to release its juices, mix it with a salt solution to break down cell membranes, and then add alcohol to separate the DNA from other cellular components. The DNA will form a visible stringy substance that can be collected using a small stick or pipette.
Why do we use ethanol to extract DNA?
Ethanol is used to extract DNA because it is able to precipitate the DNA out of solution due to its nonpolar nature. When added to a DNA solution containing salt, the DNA molecules become less soluble in ethanol and can be easily collected by precipitation with a centrifuge.

Why do you have to use alcohol to extract DNA?
Because it is less dense than the alcohol and make it float
