DNA's iconic double helix does more than "just" store genetic information. Under certain conditions, it can temporarily fold ...

For almost 60 years, scientists have tried to understand why DNA doesn't replicate wildly and uncontrollably every time a ...

Every time a cell divides, it must copy its entire genome so that each daughter cell inherits a complete set of DNA. During that process, enzymes known as polymerases race along the DNA to copy its ...

DNA doesn’t just sit still inside our cells — it folds, loops, and rearranges in ways that shape how genes behave. Researchers have now mapped this hidden architecture in unprecedented detail, showing ...

Although DNA is tightly packed and protected within the cell nucleus, it is constantly threatened by damage from normal ...

DNA, though tightly packed in the nucleus, is constantly threatened by damage from metabolism and external stressors. One particularly severe form of DNA damage is the so-called DNA–protein crosslinks ...

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 ...

If severe DNA damage is not repaired, the consequences for the health of cells and tissues are dramatic. A study led by ...

DNA is often described as the instruction manual for building the fundamental components of life. Proteins are helpers that ...
