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 ]. WebbAny mutations that are not repaired will fall into one of three categories: beneficial, harmful, or neutral (meaning they pose no harm or benefit to the individual). A mutation that is harmful will be selected against and be removed from the population.
