Our cells are constantly dividing, and as they do, the DNA molecule—our genetic code—sometimes gets broken. DNA has twin strands, and a break in both is considered especially dangerous. This kind of double-strand break can lead to genome rearrangements that are hallmarks of cancer cells, said James Daley, Ph.D., of the Long School of Medicine at The University of Texas Health Science Center at San Antonio.
