   Sammanfattning : Homing endonuclease genes (HEGs) are selfish genetic elements that mediate their own super-Mendelian inheritance. This is mediated by the homing endonuclease cleavage of a HEG- allele followed by recombination-repair with a HEG+ allele.The majority of the HEGs are encoded in intervening sequences (IVSs). LÄS MER
