I believe that the positive charged Na ions bind to the negatively charged phosphate backbone of the DNA molecule, causing an opening of the secondary (and tertiary) structure. The atoms force open the molecule through steric hindrance, similar as to why all molecules have defined angles and shape. Also, they prevent the binding of positively charged histone proteins that help wind the DNA.

Hila Road vids have got to be the best science for anyone type vids out there. Thanks! Looking forward to more.

Its the same effect as oil on water

Oil is on top of the water.

DNA is the oil

Water is the alcohol layer

[Nathaniel Gatewood]

this is a little late, lol.. But the DNA seperated out because it does no disolve in the alcohol like the other stuff does.  It's like oil and water. Oil does not dissolve in water and floats on top.

Such a nice video i ever watched!!

[SAJJJJJAD]

AWSUM....!

Why did the DNA entered the alcohol layer????

[Lynne Pedigo Riday-Reiter]

Wonderful!

DNA can be dissolved, it can be denatured into its constituent thingymagics (phosphate, base, deoxyribose sugar). Denaturation can occur from high temperature, high concentration alkaline solution, high concentration urea and high concentration of formamide

[dreddythedragon]

Of course DNA can only be seen with a powerful electron microscope but there is such a massive amount clustered together that it appears as a tissue

Thanks mate~!
