And so the majority of those DNA molecules actually break down and associate into their single strand form between the PH nine and PH ten between this range. And by the time we get to a PH of ten, we see that less than 10% of those DNA molecules inside the nucleus actually exist in their double helix form. So we see that by increasing the PH or decreasing the PH, which is not shown in this diagram, our DNA molecules begin to break down into their single strand form. The question is why? Why does this actually take place? And how does the PH actually affect that structure of the DNA molecule?
