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 ...

As expected, accuracy also depended on whether the DNA polymerase retains a 'proofreading' functionality, which verifies (and if necessary removes) any mismatched nucleotides: a version of the enzyme ...

Abbondanzieri) For a high resolution photograph click here. When Ralph Waldo Emerson said that nature pardons no mistakes, he wasn't thinking about RNA polymerase (RNAP) - the versatile enzyme that ...
