Correct Option: A
Electroporation, or electropermeabilization, is a significant increase in the electrical conductivity and permeability of the cell plasma membrane caused by an externally applied electrical field. It is usually used in molecular biology as a way of introducing some substance substance into a cell, such as loading it with a molecular probe, a drug that can change the cell’s function, or a piece of coding DNA.
