Scaffolded DNA and RNA origami is a technique that allows scientists to build tiny, highly precise two- and three-dimensional ...

Nucleotide excision repair is a DNA repair pathway which detects and fixes various DNA lesions that distort the structure of DNA. In bacteria, the pathway starts with the UvrA protein which has two ...

While most known types of DNA damage are fixed by our cells’ in-house DNA repair mechanisms, some forms of DNA damage evade repair and can persist for many years, new research shows. This means that ...

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 ...
