And so we reform that strand that we essentially broke this into. So notice that the restriction enzyme cuts at a palindromic sequence shown in blue. The cut sides are symmetrically positioned along the two strands of DNA. So we cut this region between the ga and this region also between our ga. Now, another way of saying that our mechanism of action is along a palindromic sequence is to basically say that the way we cut our double stream DNA molecule is to form a molecule that is characterized by a two fold rotational symmetry. So this should be rotational symmetry. So one interesting property of the majority of the cleavages that take place is that they are characterized by two fold rotational symmetry.
