Heat-loving Microbe Repairs Its DNA With Light
... repairing damageto its DNA," said Grogan. Grogan tested the microbe's repair capabilities by artificiallydamaging the DNA of live S. acidocaldarius cells with UVradiation, whose effects on DNA are precisely known. As expected,the vast majority of cells were unable to reproduce followingthis treatment. ...Transgenic Rice Plants Resist Insects, Drought And Salt Damage
