Answer:
DNA extraction starts with the cell or virus that needs to be studied. First, the cell is broken open. To do this, the cell is placed in a bead beating tube. Sodium acetate salt is applied to the cell to keep the proteins from degrading during the process. The detergent sodium dodecyl sulfate (SDS) is then applied to the cell to help remove the lipid membranes. It is then placed in phenol-chloroform for vortexing, to break down the proteinacious cellular walls.
