Homologous Recombination
Homologous Recombination is a biological process that occurs during cell division, particularly in meiosis and mitosis. It involves the exchange of genetic material between two similar or identical DNA molecules, typically homologous chromosomes. This exchange helps ensure genetic diversity in offspring and plays a crucial role in repairing DNA damage.
During homologous recombination, enzymes facilitate the alignment of homologous chromosomes, allowing for the precise exchange of segments. This process is essential for maintaining genetic stability and can also be harnessed in laboratory techniques, such as gene targeting and gene therapy, to modify specific genes in organisms.
