Agarose is used to separate DNA because it has a neutral charge and low chemical complexity - meaning it is unlikely to react with biomolecules. It is also an easily cast and handled matrix. Plus, samples are very easy to recover when you use agarose gel. 4 people found this useful.
When you add NaCl in a concentration between 0.4 - 0.7M, the nucleic acids stay in solution, while polysaccharides and other substances, which may interfere with the DNA preparation do not.See this paper:  Rapid isolation of high molecular weight plant DNA. . share | improve this answer. edited Dec 9 '14 at 2:16. have a question about the role of NaCl in the DNA extraction process. So for NaCl concentrations under 0.5M, CTAB and DNA molecules can create complexes.
