Sep 8, 2023 · To overcome the harmful effects of DNA damage, cells have various systems such as DNA repair mechanisms, damage tolerance pathways, cell cycle checkpoints, and cell …

There are three types of repair mechanisms: direct reversal of the damage, excision repair, and postreplication repair. Direct reversal repair is specific to the damage.

At least five major DNA repair pathways—base excision repair (BER), nucleotide excision repair (NER), mismatch repair (MMR), homologous recombination (HR) and non-homologous end …

DNA damage can be subdivided into two main types: other radiation frequencies, including x-rays and gamma rays, and particles like electrons, neutrons, or alpha particles. The replication of …

Jul 23, 2025 · Cells use different repair mechanisms, including direct reversal and nucleotide excision repair. These processes involve recognizing, removing, and replacing damaged …

DNA has many elaborate mechanisms to repair any damage or distortion. The most frequent sources of damage to DNA are the inaccuracy in DNA replication and chemical changes in DNA.

There are three modes of excision repair, each of which employs specialized sets of enzymes. The 2015 Nobel Prize in chemistry was shared by three researchers for their pioneering work …
