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

Markerless mutants using suicide vector

Are you sure that the bacteria is capable of homology recombination? Is your vector linearized? What about usage of two linear pieces which are homologous to each other?

λ Phase Genetic Switch

the λ-phage inserts his DNA by recombination; the integration is site-specific, the recognition-site is found to by 15bp long and is located between the gacactose and tryptophan genes... My thesis: as long as the plasmid DNA doesn`t contain ...

How dominance works at the DNA/RNA/protein

... when each chromosome is duplicated and 2 sister chromatids are joined at the centromere. They would be identical to each other IF there was no recombination... The rest of your reasoning is faulty at best. I’ll try to explain with another example… Suppose you have two pea plants, one gives ...
