Definitions related to recombination, genetic:
-
(dna recombination) Any process in 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. Interchromosomal recombination occurs by crossing over. In bacteria it may occur by genetic transformation, conjugation, transduction, or F-duction.Gene Ontology DictionaryGene Ontology Consortium, 2021
-
(genetic recombination) Natural process of exchange of DNA between two homologous chromosomes during mitosis; do not confuse with RECOMBINANT DNA, which applies to artificial DNA constructs.CRISP ThesaurusNational Institutes of Health, 2006
-
Production of new arrangements of DNA by various mechanisms such as assortment and segregation, CROSSING OVER; GENE CONVERSION; GENETIC TRANSFORMATION; GENETIC CONJUGATION; GENETIC TRANSDUCTION; or mixed infection of viruses.NLM Medical Subject HeadingsU.S. National Library of Medicine, 2021
-
(dna recombination process) Any type of DNA sequence rearrangement involving possible exchange and frequent loss of segments of DNA by either homologous recombination or non-homologous end-joining of broken DNA strands. Recombination is involved in assorting genes during reproduction, in repairing broken DNA, and in maintaining cell viability at the expense of long-term genomic stability.NCI ThesaurusU.S. National Cancer Institute, 2021
-
Recombination, in genetics, primary mechanism through which variation is introduced into populations. Recombination takes place during meiosis, when maternal and paternal genes are regrouped in the formation of gametes (sex cells). Recombination occurs randomly in nature as a normal event of...Encyclopedia Britannica, Inc., 2020
