If we're switching chemicals here, so that the formula for each base pair is different, then how can they call it DNA? DNA has a specific chemical formula. wouldn't they have to make up a new name for it? Does the "DNA" in this bacteria have the same double helix shape?

What makes DNA is the sugar Deoxyribose. Now the nucleic acid (the A,T,G,C part) is attached to one end and the Phosphorus, or Arsenic in this case, is attached to the other.
So as long as Deoxyribose is there it is DNA helix or not.
