DNA is the genetic information carrier molecule in the cell and thus it is very essential to keep the genetic information intact. Even though DNA holds a prime position, it is one of the highly susceptible molecules in the cells because DNA can be damaged by a number of factors both interna...

NHEJ is a non-preservative DNA repair pathway as it usually results in the loss of the damaged area (Figure 2; IVa). b) Microhomology-Mediated End Joining (MMEJ) During MMEJ, regions of microhomology are identified on one side of the DSB and single-stranded overhangs are aligned accordingly...
Humans do possess some enzymes that can undo damage with less efficiency. But we become sunburned when our DNA is too damaged for those enzymes to repair, and our skin cells die. Scientists have linked chronic sun damage to DNA mutations that lead to diseases such as skin cancer. ...

DNA repair: DNA repair is characterized as an assortment of techniques that can be used by a cell to recognize and rectify the destruction caused to the DNA molecules that code for its genome structure. It has been found that in living cells, both regular metabolic actions and environmental co...
