And let's begin by looking at inversion. So let's suppose this is our normal chromosome and this is a specific segment of the DNA that is about to break off. So let's suppose this chromosome is exposed to some type of radiation, for example, X ray radiation. And eventually the X ray radiation breaks the bonds within this section and this section. And so we have the breakage of that particular segment of DNA. Now, what happens during inversion is once this breaks off, it basically reverses its orientation and so it flips.
