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'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 ...

MSK researchers are shedding new light on G-quadruplexes, a type of secondary DNA structure that can cause DNA replication to stall. The structures are a potential therapeutic target in cancer. Image ...

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 ...

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