DNA repair is essential for the maintenance of genomic stability and its failure can lead to human disease. Various DNA repair systems exist, such as base excision repair, nucleotide excision repair, ...

Following a double-strand DNA break, an enzyme called PARP1 helps hold the two strands together —like superglue— and creates a safe zone for other proteins to come repair the damage. We don’t exactly ...

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 ...

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 ...

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 ...

Red arrows indicate the DNA repair pathways that are known to aid bacterial survival as persisters and gamblers in the presence of fluoroquinolones. Blue color arrow indicates downregulation, while ...
