The explanation given in that episode is that time travelers in the TARDIS pick up a sort of background radiation. It's largely harmless, but during the Time War the Daleks picked up on it and adapted to steal the energy for their own use. It was enough to get the Dalek moving again, and was later used in Doomsday again when Mickey touched the Dalek "Genesis Ark" prison ship.
The DNA transfer seemed to be incidental, and accidental. Daleks seem to have a lot of defenses around that sort of thing, and it probably only happened because it was so weak.
