Evolution Of Radio Resistance Is More Complicated Than Previously Thought Science Research News
Scientists select for a new strain E. coli highly resistant to radiation in the laboratory: Frontiers in Microbiology By Lucie Sammicheli, science writer Radio-resistance in bacteria first evolves through the adaptation of DNA repair mechanisms, however as evolution continues more mutations accumulate, and more cellular metabolic processes are affected. It is not yet clear which panel of mutations provides high-level resistance. The study shows that acquisition of radio-resistance via evolution is possible independent of other mechanisms like extreme dryness resistance (desiccation)....
