... The differences between DNA and RNA are that: RNA has a hydroxyl group on the 2' carbon of the sugar. Not like DNA uses thymine (T), RNA uses uracil (U). Because of the extra hydroxyl group on the sugar, RNA is too bulky to form a stable double helix. RNA exists as a single-stranded molecule. ...

Since the inhibitor has all of the same features as the true substrate, e.g. bases for BamH1 to recognize, negative charges on the backbone, etc, the binding of both DNA molecules should be the same.
