How "deep" does Mystique's powers go?

Does she change to the genetic level or only an outer shell?

Beauty is only skin deep- and sadly so is Mystique. 

The skin remains the largest change, but her power has enormous range

Whether large or small or fat or thin, it doesn't matter whose skin she is in. 

Her veins run red though her skin looks blue, but her blood is still hers no matter what she shifts into.
