Web11 apr. 2024 · DNA double-strand breaks (DSBs) are the most toxic type of lesion that occurs in DNA and can be repaired by multiple pathways. Two-ended DSBs, which are created by radiation or nucleases, can be repaired by one of three DSB repair pathways: non-homologous end joining (NHEJ), homologous recombination (HR), or … Web9 apr. 2024 · DNA replication is a highly accurate process, but errors can occur. There are several factors that can affect replication fidelity, including: DNA polymerase errors: Although DNA polymerase has proofreading activity, it is not infallible. Occasionally, errors in nucleotide selection or proofreading can occur, leading to mutations.
