DNA repair is the process by which cells correct damage to their DNA molecules. This damage can occur due to various factors such as exposure to environmental toxins, radiation, or errors during DNA replication. DNA repair mechanisms are essential for maintaining the integrity of the genome and preventing mutations that can lead to diseases such as cancer. Research in this area focuses on understanding the different pathways involved in DNA repair, identifying factors that influence repair efficiency, and developing potential therapeutic strategies for diseases caused by DNA damage.Overall, DNA repair research plays a crucial role in advancing our understanding of genetic stability and ultimately improving human health.
