The exact causes of chronic kidney failure are unknown, although the debilitating loss of healthy kidney tissue may be a natural endpoint for several readily recognizable conditions, including advanced dental disease and a variety of kidney infections, inflammations and obstructions.
Sodium chloride was needed to ensure the proteins in the cell aren't separated from the rest of the solution with the DNA. Okay, the person above does not understand Chemistry nor the English language. The sodium chloride, NaCl, is a polar molecule, which would help separate an emulsion of two layers in an acid-base extraction. Since NaCl is polar, it would be easily dissolved into the solution and tie up the different layer molecules.
Several different forms of sodium are used in DNA extraction. Sodium dodecyl sulfate, or SDS. is a sodium-containing detergent. It has the chemical formula of C12H25NaO4S, where the Na stands for sodium. Detergents are used to break down cell walls and membranes.odium hydroxide is a base. A solution of sodium hydroxide makes the solution very basic or alkaline. Sodium hydroxide can act by loosening the rigid structure of a cell wall or membrane, thereby releasing the DNA. Sodium hydroxide is most often used in plasmid DNA extraction.
