Genomic stability refers to the maintenance of the integrity and proper functioning of an organism's DNA. It ensures that genetic information is accurately replicated and passed on during cell division. This stability is crucial for preventing mutations, which can lead to diseases such as cancer. Various cellular mechanisms, including DNA repair systems and cell cycle checkpoints, work together to preserve genomic stability. When these mechanisms fail, it can result in genomic instability, increasing the risk of genetic disorders and contributing to the aging process. Maintaining genomic stability is essential for overall health and longevity.
