Now what happens is once we expose the gene to this restriction enzyme, the restriction enzyme cuts or cleaves this gene at two different locations. So at this location, somewhere here, and in this location somewhere here. So at the end, once we expose this gene to this enzyme, we get three different DNA fragments. So we have DNA fragment one, DNA fragment two, and DNA fragment three. And these fragments all came from this entire gene. Now once we obtain these fragments, we now expose the fragments to the process of gel electrophoresis.
