New study sheds light on DNA movements during nucleosome remodeling.

Our genetic material, the DNA, is packaged into a tightly condensed structure referred to as chromatin. The chromatin is in turn made up of nucleosomes which all contain a stretch of DNA wrapped around a cylinder-shaped core consisting of histone proteins. Inside the nucleosome, the DNA is largely shielded from interactions with proteins, which means […]
