DNA Repair is a vital process that helps maintain the integrity of an organism's genetic material. Cells are constantly exposed to damage from environmental factors like UV radiation and chemicals, as well as errors that occur during DNA replication. To counteract this damage, cells have developed various mechanisms to identify and fix these errors, ensuring that the genetic information remains accurate. There are several types of DNA Repair mechanisms, including base excision repair, nucleotide excision repair, and mismatch repair. Each of these processes targets specific types of damage, allowing cells to efficiently restore their DNA to its original state. Proper functioning of these repair systems is crucial for preventing mutations that can lead to diseases, including cancer.
