Answer:
In order to increase the permeability of the cell membrane.
Step-by-step explanation:
A genetic engineerer apply jolts from electricity or high heat to bacterial cell walls during transformation in order to increase the permeability of the cell membrane. Increasing permeability of the cell membrane allows the genetic engineerer to insert the desired chemicals, drugs, or DNA into the cell. If she did not increase the permeability of the cell, no or less materials pass through the membrane and there is less chance of having transformation.
