WebIn mam- malian cells, DSBs are largely repaired by either homologous recombination repair mechanism (HRR) or non-homologous end joining (NHEJ) repair mechanism [15]. The main difference in HRR and NHEJ is the obligation of a homologous DNA sequence in HRR, which is, therefore, an error-free mechanism. WebFortunately, your cells have repair mechanisms to detect and correct many types of DNA damage. Repair processes that help fix damaged DNA include: Direct reversal: Some DNA-damaging chemical reactions can be directly "undone" by enzymes in the cell. WebSection Summary. DNA replicates by a semi-conservative method in which each of the two parental DNA strands act as a template for new DNA to be synthesized. After replication, each DNA has one parental or “old” strand, and one daughter or “new” strand. Errors made during replication are typically repaired. danskin now women\u0027s athletic low bungee shoe
