abstract：:G-quadruplexes (G4s) are stable secondary structures that can lead to the stalling of replication forks and cause genomic instability. Pif1 is a 5' to 3' helicase, localized to both the mitochondria and nucleus that can unwind G4s in vitro and prevent fork stalling at G4 forming sequences in vivo. Using in vitro prime...
