Simply put, DNA Extraction is the removal of deoxyribonucleic acid (DNA) from the cells or viruses in which it normally resides. DNA is the precipitated by mixing with cold ethanol or isopropanol and then centrifuging. 2  The DNA is insoluble in the alcohol and will come out of solution, and the alcohol serves as a wash to remove the salt previously added.
Answer by Katie Ferguson. Confidence votes 69. Hmm, I think it's used to wash the DNA from the substance used for extracting the DNA, such as Isopropanol, CLS, NLS, PPS which are used in the process of extraction to the process to precipitate the DNA (using isopropanol). DNA is insoluable in alcohol.ctually the real reason for using alcohol in a DNA extraction is to precipitate (NOT RAIN) the DNA, as you may have realized when you did the experiment, the Alcohol step is the last step that brings the DNA to the surface.
