Vaccinia virus pulls together a makeshift tool to repair its DNA, exposing a vulnerability that could be targeted
Human Biology News -- ScienceDailyThe vaccinia virus uses its own machinery and not that of the cell it infects to repair ultraviolet radiation-caused damage to its DNA, according to new research. The virus repurposes an enzyme it uses for copying its DNA to repair[…]
