And it will become important when we'll discuss the hybridization process of DNA. So in the laboratory setting, if we want to actually break that double helix structure, we can either change the PH of our solution or we can increase the temperature of that solution. Now, we know that inside our body and inside our cells, we have this process of homeostasis that takes place. And what that means is the temperature nor the PH actually changes. So inside our cells, we don't change the temperature and we don't change our PH. So how exactly do we separate the DNA strands inside our cells?
