Answer 2

Procedures to isolate DNA include salting-out and binding on a solid phase support. Extraction makes use of a solvent that serves as the extractant and has two stages: (i) gentle lysis of the cells / solubilization of DNA and (ii) removal of contaminants (proteins, RNA and other macromolecules) or the so-called purification is achieved either by enzymatic or chemical means. Because of the presence of cell wall in plant samples, purification of plant DNA crude extract can be achieved by these three additional steps following lysis: precipitation, wash, and resuspension.

Hope it helps.
