TRIS maintains the pH of the solution. Basically it interacts with the lipopolysaccharides present on the outer membrane which helps to permeabilize the membrane. This effect is enhanced with the addition of EDTA.
Buffer is used to maintain pH in any process. In DNA extraction EDTA used as a chelating agent at pH8. This ensure the isolation process pure, since chelating agent inactivate the contaminating DNAses.
Trizol disrupts cells and sollubilizes cell components but maintains the integrity of RNA
it interacts with the lipopolysaccharides found in the outer membrane. by this it is helping the work of EDTA. this will cause cell lysis
In solution, NaCl can split into Na+ and Cl- ions. These ions are indeed needed to stabilise the hydrophilic residues of the protein molecule that are exposed on the surface. So NaCl is a stabilising agent in various protocols even in the extraction, but it does not has any role in lysing the cells or neutralising other biomolecules.
This might not be the best answer but, preparing a buffer solution allows one to keep the pH value the same when small amounts of acids or bases are added. Buffer solutions resist change in pH. Source: My Chemistry teacher's PowerPoint
0.2 L = cl 1 ml = 0.1 cl 240 ml = 24.0 cl 1 L = 100 cl 0.2 L = 20 cl 50 cl is bigger than 0.2 L = 20 cl and 240 ml = 24 cl
how can we convert cl in dl.
1cL = 10mL. Thus, multiply cL by 10 to get mL
In a DNA extraction, the purpose of a buffer is to solubilize DNA as well as RNA. Because of this, it prevents the DNA for degrading.
tris tris cl is 6 cl and tris hcl is 3hcl...........

Cl-Cl is more covalent than H-Cl
TE buffer is a often used as a buffer solution in molecular biology, mainly in procedures involving DNA or RNA. The purpose of TE buffer is to solubilize DNA or RNA, while protecting it from degradation.

In cl-cl bond 1 electron is sahred by each of Cl atom.
1 mole Cl = 35.453g Cl 28.4g Cl x 1mol Cl/35.453g Cl = 0.801 mole Cl
