After a DNA replicates and sister chromatids are produced, before each chromatid is divided and move opposite directions, the chromosome is supercoiled but why?

So that they can move more easily around the cell via the cytoskeleton.

By analogy it is much easier to move a bundle than a tangle of strings such as a net.
