Scientists visualize structure of key DNA repair component with near-atomic resolution (image) University of Science and Technology of China Share Print E-Mail Caption At the first hint of DNA damage, a protein known as an ATR kinase activates the cell's built-in repair system. Scientists have now imaged this protein at unprecedented resolution, and are beginning to understand its response to DNA damage.
