In electrophoresis because of the varying charges and masses, of different molecules and particles of a mixture will migrate at different velocities under uniform force and will thus be separated into single fractions.

Principle of one-way conduction at chemical synapses 

always transmit the signals in one direction i.e., from the neuron that secretes the neurotransmitter called the presynaptic neuron, to the neuron on which the transmitter acts, called the postsynaptic neuron

Introns may more freely accumulate point substitutions and other changes due to no selection pressure.  Introns evolve or accumulate mutations/changes much more rapidly than exons
