Sodium ions neutralize the negative charge of DNA to facilitate precipitation. This helps the DNA come out of the solution. Detergent emulsifies cell and nuclear membranes of cells.
Detergent contains sodium laurel sulfate, which cleans dishes by removing fats and proteins. It acts the same way in the DNA extraction protocol, pulling apart the lipids and proteins that make up the membranes surrounding the cell and nucleus. Once these membranes are broken apart, the DNA is released from the cell
The detergent separates the lipid molecules, causing the membrane to break down.
