Stalling at unrepaired forks
Webb27 dec. 2024 · If a subsequent replisome reaches unrepaired lesions, nicks, or collapsed forks, it can turn these defects into double-strand breaks, which, if not repaired, are lethal. Proper cell growth and division following replication arrest … Webb14 apr. 2024 · Unrepaired DNA damage leads to mutations, compromises cellular viability, and prevents the correct transfer of genetic material to the next generation [ 22 ]. Many cellular functions, including DNA replication and transcription, are dysregulated following failure to repair DNA [ 7, 20 ].

WebbSummary Replication forks frequently stall at regions of the genome that are difficult to replicate or contain lesions that cause replication blockage. An important mechanism for the restart of a stalled fork involves endonucleolytic cleavage that can lead to fork restoration and replication progression.
