These include direct reversal, excision repair, mismatch repair, and repair of DNA breaks.microbenotes.com/dna-damage-and-repair/During DNA synthesis, most DNA polymerases "check their work," fixing the majority of mispaired bases in a process called proofreading. Immediately after DNA synthesis, any remaining mispaired bases can be detected and replaced in a process called mismatch repair.www.khanacademy.org/science/biology/dna-as-th…Double-strand breaks, the most serious injuries that happen to DNA, can be repaired by one of two pathways: a fast but error-prone process known as NHEJ (non-homologous end joining) and a slower, error-free pathway known as HR (homologous recombination).www.salk.edu/news-release/right-way-repair-dna/Thus, enzymes known as DNA glycosylases remove damaged bases by literally cutting them out of the DNA strand through cleavage of the covalent bonds between the bases and the sugar-phosphate backbone. The resulting gap is then filled by a specialized repair polymerase and sealed by ligase.www.nature.com/scitable/topicpage/dna-damage-r…A multidisciplinary team of Indiana University researchers have discovered that the motion of chromatin, the material that DNA is made of, can help facilitate effective repair of DNA damage in the human nucleus—a finding that could lead to improved cancer diagnosis and treatment.phys.org/news/2022-09-motion-dna-linked-respons… - See more
