Definition
The processes by which cells maintain the integrity of their genetic material, including the repair of DNA damage caused by heat, UV radiation, chemicals, and free radicals, through various mechanisms such as depurination, deamination, and mismatch repair
Summary
DNA repair mechanisms are vital for maintaining the integrity of genetic information within cells. They protect against various types of DNA damage caused by environmental factors, replication errors, and other sources. Understanding these mechanisms is crucial for comprehending how cells prevent mutations that can lead to diseases such as cancer. The study of DNA repair not only sheds light on fundamental biological processes but also has significant implications in medicine and biotechnology. Advances in DNA repair research are paving the way for innovative treatments and technologies, such as gene therapy and CRISPR, which hold the potential to revolutionize how we approach genetic disorders and cancer treatment.
