Rotation of DNA in electric field

[Eagle9]

As known the DNA molecule has got negative electric charge. Imagine that linear (almost like a straight arrow) DNA is placed in water solution and we turn the electric field on. I would like to know if the DNA molecules can orientate/rotate so that they to stay along the field lines of the electric field.

I have heard that that in Pulsed-field gel electrophoresis exactly this approach is used: the electric field can orientate the DNA molecules.

So, is it possible?

What prevents them from moving towards the positive electrode?

I guess the orientation will depend on the charge distribution.

Of course nothing

Perhaps
But I want to know if they are arranged along the field lines or not
