In a controlled experiment, an independent variable (the cause) is systematically manipulated and the dependent variable (the effect) is measured; any extraneous variables are controlled. The researcher can operationalize (i.e. define) the variables being studied so they can be objectivity measured.

Answer:
Yes, with the assistance of electroporation the bacteria Enterococcus can be made competent, and afterward, the Streptococcus bacterial genes can be presented within the Enterococcus with the help of a cloning vector.
The electropermeabilization or electroporation refers to a microbiology technique in which the permeability of the cell membrane is enhanced with the application of the electric field. This permits drugs, chemicals, or DNA to get presented within the cell.
The procedure of electroporation is generally used in the field of microbiology to transform yeast, bacteria, or protoplasts of plants by presenting novel coding DNA.
