(PhysOrg.com) -- DNA is under constant attack, from internal factors like free radicals and external ones like ionizing radiation. About 10 double-strand breaks – the kind that snap both backbones of the double helix – occur every time a human cell divides. To prevent not only gene mutations but broken chromosomes and chromosomal abnormalities known to cause cancer, infertility, and other diseases in humans, prompt, precise DNA repair is essential.
