Ethanol
to precipitate extracted DNA
As DNA is completely soluble in water, but not in alcohol, like isopropanol, when isoprop is added, its engaged more and more water molecule to interact, as a result, less water molecules are available to dissolve DNA, and DNA statrs ppt out.
to extract the DNA from the solution, isopropyl alcohol is mixed with the DNA solution to precipitate the same.
To concentrate or purify the DNA, which is insoluble in isopropanol. Once the solution containing your DNA is placed in isopropanol and centrifuged, the DNA will precipitate to a little pellet at the bottom of your tube. Everything else in your tube is soluble in isopropanol and will remain in liquid form. Pipet the liquid out and now you have just DNA.
A child is unable to have DNA from two men. This is because there must be two gametes that are able to sexually reproduce.

BECAuse it does...
Sodium chloride help to precipitate and separate DNA.
Native DNA precipitates as fibers when alcohol is added to a solution containing DNA. The DNA fibers can then be spooled onto a glass rod.
yes it will precipitate DNA if your lysing nuclei; add benzamidine hydrochloride though as a protease inhibitor.

water, H2O
The alcohol used causes the precipitate to form due to a reaction allowing the hydrogen bonds between the nucleotides to form, which causes the DNA to become efficient packed and twisted together.
DNA is not soluble in isopropyl alcohol. It will precipitate out when you add this solvent. Once out of solution you can centrifuge it down and collect the pellet of DNA.
It causes it to condense or precipitate out of the soap solution.
Ethanol is used to precipitate the DNA. I.e. to bring the DNA out of solution. Precipitated DNA is then spun down and re suspended in the appropriate buffer that is suitable for sample storage
