DNA is a lengthy molecule—approximately 1,000-fold longer than the cell in which it resides—so it can't be jammed in haphazardly. Rather, it must be neatly organized so proteins involved in critical processes can access the information contained in its nucleotide bases. Think of the double helix like a pair of shoe laces twisted together, coiled upon themselves again and again to make the molecule even more compact.
