So once we expose it to these two different cleaving agents, we have two sets of fragments. And then we can use the overlapping regions of those fragments to basically piece the information together, just like in a puzzle. So to see exactly what we mean by that, let's take a look at the following example. So, in this example, we have some type of polypeptide. And when we take the polypeptide and we expose it to Trypsin, we get these two fragments. Now we take that same polypeptide in its full polypeptide form, and we now expose it to chimetrypsid, and we get three fragments that look like this.
