migration of biomolecules in electerophoresis is always towards the opposite site electrode. because there is attraction between two opposite charge
molecule with positive charge migrate toward negative electrode and molecule with negative charge migrate towards positive electrode.
DNA is negatively charge molecule (due to it phosphate backbone) so that it migrate toward the positive pole. there is attraction between two opposite charge and same charge repeals each other , so that due to negatively charge DNA molecule moves toward positive pole in gel electrophoresis.
Add Answer to:
distance Explain migration according to charge (tips - why DNA moves toward the positive polo

If a positive charge moves toward higher electric potential, what will happen to its electric potential energy? How about if it moves along an equipotential? If a negative charge moves toward higher electric potential, what will happen to its electric potential energy? How about if it moves akng an equipotential ?

please explain!
A positive charge of 4.10 C is fixed in place. From a distance of 3.80 cm a particle of mass 6.80 g and charge +3.00 C is fired with an initial speed of 80.0 m/s directly toward the fixed charge. How close to the fixed charge does the particle get before it comes to rest and starts traveling away? Submit Answer Tries 0/20 e Post Discussion Send Feedback

A positive charge, +q, of mass m is moving at speed vo toward a second positive charge, +Q, when it is at an initial distance, R, away. The second charge, +Q, is assumed to be fixed in position. Also assume that any changes in gravitational potential energy are negligible. Derive an expression for the closest distance (call this r) charge +q gets to + before it changes position Enter your answer in terms of R, vo. Q. q, m and...

2. Explain why electroosmotic flow predominates capillary electrophoresis and how it can affect the migration (elution) of positive, negative, and neutral species within a sample.
If a positive charge moves toward higher electric potential, what will happen to its electric potential energy? How about if it moves along an equipotential? If a negative charge moves toward higher electric potential, what will happen to its electric potential energy? How about if it moves akng an equipotential ?
