The human genome consists of 3 billion base pairs, and when a cell divides, it takes about seven hours to complete making a copy of its DNA. That's almost 120,000 base pairs per second. At that ...

Researchers have discovered how cells activate a last-resort DNA repair system when severe damage strikes. When genetic tangles overwhelm normal repair pathways, cells flip on a fast but error-prone ...

A new fluorescent sensor is giving scientists an unprecedented view of how cells respond to DNA damage, capturing the repair process as it unfolds in real time. The tool, developed at Utrecht ...

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 ...

The DNA inside our cells is constantly being damaged, and one of the worst kinds of damage is a double-strand break-when both sides of the DNA helix are cut at once. Healthy cells can normally fix ...
