Break-induced replication promotes formation of lethal joint molecules dissolved by Srs2
Break-induced replication (BIR) is a double-strand break repair pathway that can lead to genomic instability. Here the authors show that the absence of Srs2 helicase during BIR leads to uncontrolled binding of Rad51 to single-stranded DNA, which promotes the formation of toxic intermediates that nee...

| Sumario: | Break-induced replication (BIR) is a double-strand break repair pathway that can lead to genomic instability. Here the authors show that the absence of Srs2 helicase during BIR leads to uncontrolled binding of Rad51 to single-stranded DNA, which promotes the formation of toxic intermediates that need to be resolved by Mus81 or Yen1. |
