The DNA molecule is chemically unstable, giving rise to DNA lesions of various kinds. That is why DNA damage detection, signaling and repair, collectively known as the DNA damage response, are needed. The DNA damage response ...

Sites where DNA is damaged may cause a molecule that slides along the DNA strand to scan for damage to slow on its patrol, delaying it long enough to recognize and initiate repair. The finding suggests that the delay itself ...

Our genomes encounter DNA damaging events continuously. As damage accumulates, our cells react and stop the cell division process, giving repair mechanisms time to act. To achieve this, two master protein kinases called ATR ...
