recombination

listen to the pronunciation of recombination
English - Turkish
English - English
The reverse of dissociation
Combination a second or subsequent time
The formation of genetic combinations in offspring that are not present in the parents
{n} a second combination
as crossover
The formation of new combinations of genes Recombination occurs naturally in plants and animals during the production of sex cells (sperm, eggs, pollen) and their subsequent joining in fertilization In microbes, genetic material is recombined naturally during conjugation
In genetics, regrouping of the maternal and paternal genes during the formation of sex cells (gametes). Recombination occurs randomly in nature as a normal event of meiosis. It is enhanced by crossing-over (see linkage group). Recombination acts to ensure that no two daughter cells are identical, nor are any identical in genetic content to the parent cell. Laboratory study of recombination has contributed significantly to the understanding of genetic mechanisms, allowing scientists to map chromosomes, identify linkage groups, isolate the causes of certain genetic mistakes, and manipulate recombination itself by transplanting genes from one chromosome to another.

State in which the gasses normally formed within the battery cell during its operation, are recombined to form water
The process by which progeny derive a combination of genes different from that of either parent In higher organisms, this can occur by crossing over See also: crossing over, mutation
Recombinant DNA is produced when genetic informationfrom more than one organism is recombined in a laboratory process into a hybrid molecule Source: PhRMA Genomics
(genetics) a combining of genes or characters different from what they were in the parents (physics) a combinng of charges or transfer of electrons in a gas that results in the neutralization of ions; important for ions arising from the passage of high-energy particles
Formation in offspring of genetic combinations not present in parents
The formation in offspring of combinations of genes not present in either parent This results from the assortment of chromosomes and their genes during the production of gametes and the subsequent union of different sorts of gametes at fertilization
(genetics) a combining of genes or characters different from what they were in the parents
The process of crossing over of portions of one chromosome to another during meiosis (a type of cell division) The resulting chromosome has some of its original genes, and some of the genes from the other member of the pair
(physics) a combinng of charges or transfer of electrons in a gas that results in the neutralization of ions; important for ions arising from the passage of high-energy particles
Crossing over A phenomenon, also known as recombination, that sometimes occurs during the formation of sperm and egg cells (meiosis); a pair of chromosomes (one from the mother and the other from the father) break and trade segments with one another
State in which the hydrogen and oxygen gases normally formed within the battery cell during charging are recombined to form water
physical and breakage and reunion of chromosomal DNA
Process whereby homologous chromosomes exchange segments during meiosis
We will use it in the context of it being the process whereby electrons and holes (carriers) are annihilated, or destroyed
(See Crossing over )
process of electrons becoming bound to protons to make neutral atoms
The natural process of breaking and rejoining DNA strands to produce new combinations of genes and, thus, generate genetic variation Gene crossover during meiosis
{i} creation of new combinations of genes under natural or laboratory conditions (Genetics)
Following independent assortment of chromosomes, new arrangements of hereditary units produced through bisexual reproduction
formation of new combinations of genes as a result of the sexual process
The process by which a positive and a negative ion join to form a neutral molecule or other neutral particle, also process by which radicals or dissociations species join to form molecules
the reciprocal exchange of portions of two homologous chromosomes (usually equivalent) during gamete formation
Combination of an electron and a hole in a semiconductor that releases energy, leading to light emission
Combination a second or additional time
The process of joining together of ions and free electrons to form neutral atoms or molecules
recombination energy
The energy released when two oppositely charged fragments of an atom or molecule recombine to form a neutral compound
homologous recombination
The exchange of DNA between regions of homologous chromosomes that occurs during meiosis
radiative recombination
the capture of a free electron by an atom and the subsequent emission of a photon having the same energy
gene recombination
{i} creation of new combinations of genes under natural or laboratory conditions (Genetics)
genetic recombination
The exchange of genetic material between homologous chromosomes in meiosis
genetic recombination
a normal process that occurs during meiosis (sexual reproduction) when the DNA is replicated (an identical copy of a strand is made) DNA is cleaved and the fragments are rejoined to give new strands This allows genetic information from maternal and paternal chromosomes to be incorporated into a new genome The chances that nucleotides from one strand will cross and be on separate DNA strands increases with increasing distance between them Thus genes that lie close together on the genome are more likely to be inherited together
genetic recombination
general term for the production of an offspring that combines traits from two parents Submitted by Amy Franzen, franzena@pilot msu edu
