(Phys.org)—A team of researchers from France and Denmark, working at Institut Pasteur, in Paris has found the mechanism that is involved that allows dual chromosomes in Vibrio cholerae cells to split at the same time as ...
If you have a soft spot for unsung heroes, you'll love a DNA repair protein called XPG. Scientists from the U.S. Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab) discovered that XPG plays a previously ...
