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 ...

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 ...

A recent study in Nature Communications examined how RNA polymerase I (Pol I) responds to abasic (Ap) site formation—the most common type of DNA damage. The researchers found that Pol I helps maintain ...
