Answer: See the explanation for complete explanation.
Step-by-step explanation:
Alright, so normally in Washing Liquid and Detergents they contain sodium laurel sulfate, which cleans dishes by removing fats and proteins. It acts the same way in the extraction of DNA, 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.
Salt however, is different, it can trigger osmosis by attracting the water and causing it to move toward the membrane. Being solute, salt diffuses, spreading out the concentration that creates a solution.
Hope this helps!
