NaCl help the precipitation and separation of DNA.
Salt is used to separate DNA.

Sodium chloride help to precipitate and separate DNA.
NaCl provides Na+ions which form ionic bond with the negatively charged phosphate of DNA,thus neutralizing the effect of negative ,negative repulsion of DNA and helps the DNA molecules to come closer and compact to simplify our process of DNA isolation...

NaCl provides Na+ ions that will block negative charge from phosphates on DNA. Negatively charged phosphates on DNA cause molecules to repel each other. The Na+ ions will form an ionic bond with the negatively charged phosphates on the DNA, neutralizing the negative charges and allowing the DNA molecules to come together
Sodium chloride help the separation of DNA from other proteins.
NaCl stabilizes the the double helical structure of DNA. It also provides Na+ that neutralise the negative charge present on DNA. Due to the negative charge the DNA molecules repell each other. When the charge is neutralized the DNA molecule come together and could be precipitated.
dna binding protein binds the 2 anti parallel strands of dna together
Salt soap helps break down cell membranes, releasing DNA from cells. Ethanol is added to DNA-containing solution to precipitate DNA out of solution, as DNA is not soluble in ethanol. The DNA can then be collected by spooling or centrifugation.
restriction enzymes on DNA molecules.
Every action figure in the Ben 10 series has a different secret DNA code. Each Keven 11 action figure has a different secret DNA code. The only way to find out the code is to purchase an action figure.
Sodium chloride was needed to ensure the proteins in the cell aren't separated from the rest of the solution with the DNA.
