Instead, the linear DNA molecules found in our own cells and the circular DNA molecules found in bacterial cells are going to condense via this process of super coiling. Now, super coiling basically serves two important biological purposes. Number one, we actually want to be able to fit that long DNA molecule into the nucleus of our own cells and into the cell structure of that biological cell. 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.
