These oppositely charged ions attract each other on opposite faces of the membrane, generating a charge separation, or electric potential, across the membrane.

Steps of nick translation- 

Low concentrations of DNase I are used to make occasional single-strand nicks in the double-stranded DNA that is intended as the gene probe.

DNA polymerase then fills in the nicks, using an appropriate dNTP, at the same time making a new nick to the 3′ side of the previous one.
