Genetic recombination

Genetic recombination is the process by which a strand of the genetic material (usually DNA; but can also be RNA) is broken and then joined to the end of a different DNA molecule.

Genetic recombination is the process by which the combination of genes in an organism's offspring becomes different from the combination of genes in that organism.

Genetic recombination The process by which a fragment of DNA from one molecule (chromosome, plasmid, phage genome) is exchanged with or integrated into another molecule to produce a recombinant molecule(s).

genetic recombination The general term for the production of offspring that combine traits of the two parents. genome ...

genetic recombination Crossing-over; a major source of genetic variation in a population or a given species.

Gene map -- the linear arrangement of mutable sites on a chromosome as deduced from genetic recombination experiments. Gene therapy -- addition of a functional gene or group of genes to a cell by gene insertion to correct an hereditary disease.

>like a tomato plant that glows due to genetic recombination with the >enzyme luciferase that makes a firefly light up. Kids always think this >is cool and it piques their interest, but usually then leads to ...

Holliday intermediate An intermediate in genetic recombination in which two double-stranded DNA molecules are joined by virtue of a reciprocal crossover involving one strand of each molecule.

Bacteria can accomplish genetic recombination in three ways. Conjugation, shown in Figures 11 and 12, is the process where one bacterium passes DNA to another through a tube (the sex pilus) that temporarily joins the two conjugating cells.

During the formation of sperm and egg cells, a process of genetic recombination -- or "crossing over" -- occurs in which pieces of genetic material are swapped between paired chromosomes.

Homologous recombination is a type of genetic recombination that occurs during meiosis (the formation of egg and sperm cells).

Generated by base pairing between complementary single strands derived from different parental duplex molecules; heteroduplex DNA molecules occur during genetic recombination in vivo and during hydridization of different but related DNA strands in ...

The integration itself is a sequential exchange (see genetic recombination) via a Holliday structure and requires both the phage protein int and the bacterial protein IHF (integration host factor). Full article '"/ See more about: Holliday structure ...

Chiasma (plural chiasmata) Literally a cross. The point at which a genetic recombination event has occurred, visible as a cross-over in meiotic prophase.

transduction (t) The transfer of DNA sequences from one bacterium to another via lysogenic infection by a bacteriophage (transducing phage). Genetic recombination in bacteria mediated by bacteriophage.

An agent that causes a permanent genetic change in a cell. Does not include changes occurring during normal genetic recombination. Mutagenicity ...
