And to do that, we have to basically condense the structure into this super coiled form, into this very compact form that is much, much smaller. Now, the second function of super coiling is to basically affect the different types of processes found inside our body. For example, when inside our nucleus of the cell we replicate DNA, we have to unwind that double helix structure. And when we unwind that double helix structure, the process of super coiling can basically stabilize that unwinding process. And we'll discuss exactly how that takes place when we'll focus on DNA replication. So the point is, inside the cells of these living organisms, these DNA molecules don't simply exist as linear DNA molecules or as circular DNA molecules.
