• The Conductive segment is equivalent to the length of the axon. It contains voltage-gated channels.

• The Transmissive segment includes the synaptic knob and contains voltage-gated channels and Pumps.

the dna molecules have a negative charge because of the phosphate groups in their sugar-phosphate backbone, so they start moving through the matrix of the gel towards the positive pole. power is turned on and dna fragments migrate through gel (towards the positive electrode).
