Study examines how DNA damage is repaired by antioxidant enzymes

Thursday, June 1, 2023 - 05:03 in Biology & Nature

A typical human cell is metabolically active, roaring with chemical reactions that convert nutrients into energy and useful products that sustain life. These reactions also create reactive oxygen species, dangerous by-products like hydrogen peroxide which damage the building blocks of DNA in the same way oxygen and water corrode metal and form rust. Similar to how buildings collapse from the cumulative effect of rust, reactive oxygen species threaten a genome's integrity.
