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.
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.
