Genetic recombination is the breaking and rejoining of DNA strands to form new molecules of DNA encoding a novel set of genetic information. Recombination can occur between similar molecules of DNA, as in the homologous recombination of chromosomal crossover, or dissimilar molecules, as in non-homologous end joining. V(D)J recombination in organisms with an adaptive immune system is a type of genetic recombination that helps immune cells rapidly diversify to recognize and adapt to new pathogens. Recombination is a common method of DNA repair in both bacteria and eukaryotes.

Famous quotes containing the word genetic:
“Nature, we are starting to realize, is every bit as important as nurture. Genetic influences, brain chemistry, and neurological development contribute strongly to who we are as children and what we become as adults. For example, tendencies to excessive worrying or timidity, leadership qualities, risk taking, obedience to authority, all appear to have a constitutional aspect.”
—Stanley Turecki (20th century)
