EPFL Jul 28 2025 Each cell in our bodies carries about two meters of DNA in its nucleus, packed into a tiny volume of just a few hundred cubic micrometers-about a millionth of a milliliter. The cell manages this by winding the strings of DNA around protein spools. The protein-DNA complexes are called nucleosomes, and they ensure that DNA is safely stored. But this packaging into nucleosomes also poses a challenge: important cellular machinery must still access the genetic code to keep cells
