If the DNA within a cell is not separated from the cytoplasm, then that cell is a prokaryote. All known prokaryotes, such as bacteria and archaea, are single cells. In contrast, if the DNA is partitioned off in its own membrane-bound room called the nucleus, then that cell is a eukaryote.
Extracting DNA involves a series of steps to gently break open the cell, break open the nuclear membrane, separate the DNA from proteins and then cause it to precipitate out of a solution.This is accomplished using various chemicals, based on the structure of membranes, DNA and its electronegativity.Sodium chloride, or other sodium-containing compounds, are used to stabilize the DNA after it has been stripped of its proteins and aid in precipitation.o recover DNA for further testing or visualization, the DNA must be precipitated out of a solution with water. Since water has a relatively weak positive charge, this is accomplished by providing a stronger positively charged ion in the solution. Sodium is the perfect candidate for this.
