Scientists have found that twisting structures in DNA long mistaken for knots are actually something else entirely. Inside cells, DNA gets twisted, copied, and pulled apart. The twists can influence ...

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 ...

In everyday life, our genetic material is constantly under attack from many factors. Environmental influences such as light, along with internal processes like inflammation, can generate oxidative ...

DNA's iconic double helix does more than "just" store genetic information. Under certain conditions, it can temporarily fold into unusual shapes. Researchers at Umeå University, Sweden, have now shown ...

No “sticky ends”? No problem. A new study by NYU chemists finds that DNA tiles can assemble into 3D structures without the sticky cohesion of hydrogen bonding. This finding, published in Nature ...

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 ...
