In lab we did a DNA extraction from a strawberry. We got a lecture on it, but the one thing I can't remember is how the detergent lyses the cell. Can some one explain that to me?

thanks

Detergents lyse the cells by rendering the outer bilipid layer soluble. This is achieved by a process called micelle formation.
When excess of the detergent is added it incorporates the lipids in its hydrophobic core and forms a sort of circular structure with the hydrophilic groups facing the solvent ( water) and the hydrophopic core facing inwards. This is how it solubilizes the lipid bilayer.

The detergent disrupts the cell membrane by solubilizing the lipid bilayer. I imagine you had to grind the tissue as well though, that would take care of the cell wall.
