Poly(ADP‐ribose) polymerases (PARPs) are a family of enzymes that play a crucial role in maintaining genomic integrity by detecting DNA damage and facilitating its repair. By catalysing the covalent ...

When an SSB appears, polymerase epsilon approaches the nick before retracing its steps thanks to its exonuclease, allowing fork reversal to take place. The nick is repaired as an SSB, and replication ...

Researchers from Tokyo Metropolitan University have identified key factors in the mechanism behind DNA repair in our bodies. For the first time, they showed that the "proofreading" portion of the DNA ...

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 ...

DNA repair proteins act like the body's editors, constantly finding and reversing damage to our genetic code. Researchers have long struggled to understand how cancer cells hijack one of these ...

PCR, or Polymerase Chain Reaction, is a revolutionary molecular biology technique that allows for the rapid amplification of specific DNA sequences. It is an essential tool in various fields, ...

A principle of DNA synthesis that has dominated biology textbooks for decades could be upended. An enzyme has been discovered ...

A common hallmark of viral genome replication is a high mutation rate, which can aid in their ability to evade new treatments and acquire resistance to once-effective antiviral medications. Now, a new ...

Humans and baker's yeast have more in common than meets the eye, including an important mechanism that helps ensure DNA is copied correctly, reports a pair of studies published in the journals Science ...
