So for this particular example, let's suppose we add some sort of restriction enzymes that looks for this specific Palindromic sequence. What the enzyme does is it finds that Palindromic sequence and it cuts at a specific location along that DNA molecule. So for example, let's say this restriction enzyme that we add cuts between the A bases, between the adenine bases along this specific Palindromic sequence. So that means because we have two A's here and two A's here, we have the restriction enzyme cuts not only here, but it also cuts here. And once we cut those single strand molecules, these hydrogen bonds basically dissociate and we form the following molecule. So now we basically have this asymmetric uneven cut.
