DNA damage response
The DNA damage response (DDR) is a cellular process that detects and repairs damage to DNA, the genetic blueprint of living organisms. This damage can result from various factors, including environmental stress, radiation, or errors during cell division. When DNA is damaged, the DDR activates a series of signals that halt cell division, allowing the cell to repair the damage. If the damage is too severe, the DDR can also trigger programmed cell death to prevent the potential development of diseases like cancer. Essentially, DDR helps maintain the integrity of our genetic information, ensuring healthy cell function.
