Study shows how proteins work in concert to resolve DNA double-strand breaks – News-Medical.net

From cancer treatment to sunlight, radiation and toxins can severely damage DNA in both harmful and healthy cells. While the body has evolved to efficiently treat and restore damaged cells, the mechanisms that allow this natural repair remain misunderstood.
In a new study, Northwestern University researchers have used cryogenic electron microscopy (cryo-EM) to visualize this process by illuminating the mysterious cycle of DNA breakage sensing and repair. The researchers believe this new information…
