Molecular biology: Damage control
Claus M. Azzalin1 & Joachim Lingner1
Abstract
The chemical composition of normal DNA at the end of chromosomes does not differ from that of damaged and broken DNA within chromosomes. New findings hint at how the DNA-repair machinery distinguishes the two.
The maintenance of genome integrity is crucial for the survival of every organism. So even a single break along a chromosome triggers a molecular signalling cascade that leads to an appropriate DNA-damage response (DDR).
