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 ...

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

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

Scientists have created a live-cell DNA sensor that reveals how damage appears and disappears inside living cells, capturing the entire repair sequence as it unfolds. Instead of freezing cells at ...

DNA can sustain serious injuries called double strand breaks, in which both strands of the helix snap. These breaks are among the most dangerous forms of DNA damage and immediately trigger the cell's ...

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