Following a double-strand DNA break, an enzyme called PARP1 helps hold the two strands together —like superglue— and creates a safe zone for other proteins to come repair the damage. We don’t exactly ...
They have used 'magnetic tweezers', a nanotechnology technique that measures how much a single DNA molecule is stretched. The work is published in Cell Reports. "Understanding this mechanism could ...
Your DNA is continually damaged by sources both inside and outside your body. One especially severe form of damage called a double-strand break involves the severing of both strands of the DNA double ...
