Adventitious changes in cellular DNA can endanger the whole organism, as they may lead to life-threatening illnesses like cancer. Researchers at LMU now report how byproducts of respiration cause mispairing of subunits in the double helix. The DNA in our cells controls the form and function of every cell type in our bodies. The instructions for this are encoded in the linear sequence of the four subunits found in DNA, the bases adenine (A), cytosine (C), guanine (G) and thymine (T)...
