Recombination

Definition

noun, plural: recombinations

(1) (genetics) The process or act of exchanges of genes between chromosomes, resulting in a different genetic combination and ultimately to the formation of unique gametes with chromosomes that are different from those in parents.

(2) (general) The process or act of bringing together (dissociated materials) once more.


Supplement

In genetics, recombination occurs during meiosis when chromosomes exchange genes. Thus, recombination is one of the important means to promote and increase genetic diversity between generations.


Word origin: re- (again) + combination

Holliday Model of Homologous Recombination VIDEO MISTAKE?

Hello, In class today the teacher said there is something wrong with the following animation of the "Holliday Model of Homologous Recombination": http://www.youtube.com/watch?v=bkoJOZCoOOg She didn't say what it is but I will have to know this on the test very accurately and the ...

Re: Year 11 Meiosis helpp!!!

During the first part of meiosis (prophase 1) there can be recombination (crossover) of homologous chromosomes. This would show up on your diagram as being a little bit of red on one arm of the blue X, and a matching little bit of blue in the same place ...

Why must we avert the genome of Eden?

... perfect sense in contrast to the incoherent polemics of the Darwinian approach. The purpose of genders is a bit more theoretical issue. Genetic recombination does not justify the existence of genders, it can work without them. To demonstrate the concept, let me use an analogy: Let's say we have ...

meiome and genome

... meiotic transcriptome.[1][2] Meiosis is a key feature for all sexually reproducing eukaryotes in which homologous chromosome pairing, synapse and recombination occur. In addition to strong meiotic stage-specific expression of mRNA (the meiome), however, there are also pervasive translational controls ...

How a gene detect where to insert after injected to nucleus

That depends whether you add some homology sequences and homology recombination will be used to incorporate that gene. Honestly, I don't know, what's the ratio of HR and NHEJ in human.
