The extraction of DNA from a cell is often a first step for scientists who need to obtain and study a gene. The total cell DNA is used as a pattern to make copies (called clones) of a particular gene. These copies can then be separated away from the total cell DNA, and used … In the process of DNA extraction, we need to break down the nuclear envelope in order to access the DNA. This would expose the DNA to nucleases and if we don't deactivate these enzymes, they will cut and damage the DNA. Nucleases need divalent cations such as Mg2+ to function. In order to deactivate these enzymes we use EDTA which stands for Ethylenediaminetetraacetic acid to our sample tissue
