A process of DNA recombination occurring within a plasmid or between plasmids and other plasmids or DNA molecules. The reverse transcription of an RNA molecule followed by recombination between the resultant cDNA and its homologous chromosomal allele. Any cellular metabolic process involving nucleic acids. The chemical reactions and pathways involving macromolecules, any molecule of high relative molecular mass, the structure of which essentially comprises the multiple repetition of units derived, actually or conceptually, from molecules of low relative molecular mass, as carried out by individual cells. The cleavage and rejoining of intermediates, such as Holliday junctions, formed during DNA recombination to produce two intact molecules in which genetic material has been exchanged. Recombination occurring within or between DNA molecules in somatic cells. 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. The cell cycle process whereby genetic information is transferred from one helix to another. It often occurs in association with general genetic recombination events, and is believed to be a straightforward consequence of the mechanisms of general recombination and DNA repair. For example, meiosis might yield three copies of the maternal version of an allele and only one copy of the paternal allele, indicating that one of the two copies of the paternal allele has been changed to a copy of the maternal allele. The exchange, reciprocal or nonreciprocal, of genetic material between one DNA molecule and a homologous region of DNA that occurs during mitotic cell cycles. Any process involved in a type of transpositional recombination which occurs via a DNA intermediate. Lateral transfer of an intron to a homologous allele that lacks the intron, mediated by a site-specific endonuclease encoded within the mobile intron. The rejection of the broken 3' single-strand DNA molecule that formed heteroduplex DNA with its complement in an intact duplex DNA. The Watson-Crick base pairing in the original duplex is restored. The rejected 3' single-strand DNA molecule reanneals with its original complement to reform two intact duplex molecules. The molecular events that lead to the integration of a viral genome into the host genome. During meiosis, the formation of a stable duplex DNA that contains one strand from each of the two recombining DNA molecules. The re-formation of a broken phosphodiester bond in the DNA backbone, carried out by DNA ligase, that contributes to DNA recombination. The process in which the nucleoprotein complex (composed of the broken single-strand DNA and the recombinase) searches and identifies a region of homology in intact duplex DNA. The broken single-strand DNA displaces the like strand and forms Watson-Crick base pairs with its complement, forming a duplex in which each strand is from one of the two recombining DNA molecules. A DNA repair process that involves the exchange, reciprocal or nonreciprocal, of genetic material between the broken DNA molecule and a homologous region of DNA. Any process that modulates the frequency, rate or extent of DNA recombination, a 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. Any process that activates or increases the frequency, rate or extent of DNA recombination. Any process that stops, prevents or reduces the frequency, rate or extent of DNA recombination. Genetic recombination within the DNA of the genes coding for ribosomal RNA. The cell cycle process whereby double strand breaks are formed and repaired through a double Holliday junction intermediate. This results in the equal exchange of genetic material between non-sister chromatids in a pair of homologous chromosomes. These reciprocal recombinant products ensure the proper segregation of homologous chromosomes during meiosis I and create genetic diversity.
