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 ...

For almost 60 years, scientists have tried to understand why DNA doesn’t replicate wildly and uncontrollably every time a cell divides – which they need to do constantly. Without this process, we ...

Humans and baker's yeast have more in common than meets the eye, including an important mechanism that helps ensure DNA is copied correctly, reports a pair of studies published in the journals Science ...

Researchers at The University of Texas Medical Branch (UTMB) have identified how a key enzyme called ATR protects DNA from breaking when cells copy damaged genetic material, a discovery that could ...

GALVESTON, Texas — Researchers at The University of Texas Medical Branch (UTMB) have identified how a key enzyme called ATR protects DNA from breaking when cells copy damaged genetic material, a ...

Studying how single DNA molecules behave helps us to better understand genetic disorders and design better drugs. Until now however, examining DNA molecules one-by-one was a slow process.

Every cell in every organism on Earth copies DNA the same way. Except one bacterial protein — quietly doing something ...

Loss of an enzyme necessary for a process called lipoylation disrupts the way cancer cells copy their DNA, increasing their vulnerability to a class of anticancer drugs known as PARP inhibitors, a ...
