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 ...

The DNA packed inside every human cell contains instructions for life, written in billions of letters of genetic code. Every time a cell divides, the complete code, divided among 46 chromosomes, must ...

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 ...

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 ...

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 ...

A protein that is involved in determining which enzymes cut or unwind DNA during the replication process has been identified. A protein that is involved in determining which enzymes cut or unwind DNA ...

Research team led by Nagoya University develop a label-free method for detecting DNA amplification in real time based on refractive index changes in diffracted light. Polymerase chain reaction (PCR) ...
