Which sequences make DNA unwrap and breathe?

(Springer) Accessing DNA wrapped into basic units of packaging depends on the underlying sequence of the building blocks. Like Christmas presents, some nucleosomes are easier to unwrap than others before genes are expressed. In a new study published in EPJ E, Jamie Culkin from Leiden University, the Netherlands, and colleagues demonstrate the role of the DNA sequence in making it possible for packaged DNA to open up and allow genes to be read and expressed.
