Genome stability refers to the maintenance of the integrity and proper function of an organism's DNA. It ensures that genetic information is accurately replicated and passed on during cell division. Any disruptions to this stability can lead to mutations, which may result in diseases such as cancer. Several mechanisms contribute to genome stability, including DNA repair systems that fix errors, cell cycle checkpoints that monitor and regulate cell division, and chromosome segregation processes that ensure proper distribution of genetic material. Together, these systems help preserve the genetic blueprint essential for healthy growth and development.
