Lateral transfer of a group I intron to a homologous allele that lacks the intron, mediated by a site-specific endonuclease encoded within the mobile intron; group I introns are self-splicing introns that use guanosine as a cofactor in the splicing reaction. Any process by which a new genotype is formed by reassortment of genes resulting in gene combinations different from those that were present in the parents. In eukaryotes genetic recombination can occur by chromosome assortment, intrachromosomal recombination, or nonreciprocal interchromosomal recombination. Intrachromosomal recombination occurs by crossing over. In bacteria it may occur by genetic transformation, conjugation, transduction, or F-duction. Any cellular metabolic process involving deoxyribonucleic acid. This is one of the two main types of nucleic acid, consisting of a long, unbranched macromolecule formed from one, or more commonly, two, strands of linked deoxyribonucleotides. Lateral transfer of an intron to a homologous allele that lacks the intron, mediated by a site-specific endonuclease encoded within the mobile intron. Lateral transfer of a group II intron to a homologous allele that lacks the intron, mediated by a site-specific endonuclease encoded within the mobile intron; group II introns are self-splicing introns with a conserved secondary structure.
