Scientists Discover a Genetic Code for Organizing DNA
Weizmann Institute of ScienceDNA "“ the long, thin molecule that carries our hereditary material "“ is compressed around protein scaffolding in the cell nucleus into tiny spheres called nucleosomes. The bead-like nucleosomes are strung along the entire chromosome, which is itself folded and packaged to fit into the nucleus. What determines how, when and where a nucleosome will be positioned along the DNA sequence?
