DNA repair is a well-known cellular defense mechanism responsible for maintaining the genome integrity. Cell cycle checkpoints can be activated by genotoxic stress and delay cell cycle progression to allow the DNA repair response (Bao et al., 2001 ).
Is there a way to repair DNA damage?
Yes; when there is damage, there is repair as well. There is an inbuilt DNA repair mechanism that helps to correct and repair any damage caused in a DNA molecule. There are different ways by which repair of DNA takes place. This includes repair DNA naturally and repair DNA by use of different mechanisms. 1.
What happens to DNA when it is damaged?
It is also well known that a cascade of signals namely DNA damage response or DDR is activated in response to DNA damage which comprise cellular responses, such as cell cycle arrest, DNA repair and cell death, if the damage is irreparable.
