Science Buddies: What Duration of Ultraviolet Exposure Kills Bacteria?
Ultraviolet light can damage DNA molecules. If a cell's DNA repair mechanisms can't keep up with the damage, mutations are the result. As harmful mutations accumulate, the cell eventually dies. How much ultraviolet light is too much for...
