How is salt used in dna extraction

Web3 nov. 2024 · Salt or cations, present in solution play an important role in DNA denaturation and folding kinetics of DNA helix. The melting temperature increases logarithmically with the salt concentration of the solution. The more GC base pairs in the chain enhance the stability of DNA chain at a fix salt concentration. Web24 dec. 2024 · What is the role of the salt NaCl in the DNA extraction procedure? Sodium chloride helps to remove proteins that are bound to the DNA. It also helps to keep the proteins dissolved in the aqueous layer so they don’t precipitate in the alcohol along with the DNA. Ethanol or isopropyl alcohol causes the DNA to precipitate.
