Recombination occurs when two molecules of DNA exchange pieces of their genetic material with each other. One of the most notable examples of recombination takes place during meiosis (specifically, during prophase I), when homologous chromosomes line up in pairs and swap segments of DNA

∙ 11y agoDNA recombination occurs during prophase I of meiosis. During prophase I, the homologous chromosomes pair up and form tetrads. One member of each homologous pair comes from the mother and the other comes from the father. During this time, non-sister chromatids from the opposite homologous chromosomes cross over and form synapses, during which exchanges of sections of the non-sister chromatids occur. As a result, each chromatid will contain genetic material from both parents, recombining the DNA from both parents.

What type of genetic recombination in bacteria involves DNA transfer by viruses?
There are many ways that genetic recombination could occur in bacteria. One way that it occurs is because of habitat.
What is recombination?
Genetic recombination is the process by which a strand of genetic material (usually DNA; but can also be RNA) is broken and then joined to a different DNA molecule. In eukaryotes recombination commonly occurs during meiosis as chromosomal crossover between paired chromosomes. This process leads to offspring having different combinations of genes from their parents and can produce new chimeric alleles.Genetic recombination is the process by which two DNA molecules exchange genetic information, resulting in the production of a new combination of alleles. In eukaryotes, genetic recombination during meiosis can lead to a novel set of genetic information that can be passed on to progeny. Most recombination is naturally occurring. During meiosis in eukaryotes, genetic recombination involves the pairing of homologous chromosomes. This may be followed by information exchange between the chromosomes. The information exchange may occur without physical exchange (a section of genetic material is copied from one chromosome to another, without the donating chromosome being changed)(see SDSA pathway in Figure); or by the breaking and rejoining of DNAstrands, which forms new molecules of DNA (see DHJ pathway in Figure). Recombination may also occur during mitosis in eukaryotes where it ordinarily involves the two sister chromosomes formed after chromosomal replication. In this case, new combinations of alleles are not produced since the sister chromosomes are usually identical. In meiosis and mitosis, recombination occurs between similar molecules (homologs) of DNA. In meiosis, non-sister homologous chromosomes pair with each other so that recombination characteristically occurs between non-sister homologues. In both meiotic and mitotic cells, recombination between homologous chromosomes is a common mechanism used in DNA repair.Genetic recombination and recombinational DNA repair also occurs in bacteria and archaea.Recombination can be artificially induced in laboratory (in vitro) settings, producing recombinant DNA for purposes including vaccinedevelopment.V(D)J recombination in organisms with an adaptive immune system is a type of site-specific genetic recombination that helps immune cells rapidly diversify to recognize and adapt to new pathogens.

Genetic recombination is possible because of?
new combinations of genes from two parents
What effect does crossing over in propahse 1 have on the cells?
Crossing over creates a genetic recombination of the DNA.
What is called when adding on DNA to DNA?
RECOMBINATION

What is it called when you are removing a section of DNA to be used for recombination?
Removing a section of DNA to be used for recombination is called
What is the definition of recombination of genetic material?
DNA recombination refers to the phenomenon whereby two parental strands of DNA are tied together resulting in an exchange of portions of their respective strands. DNA recombination results in the process leads to new molecules of DNA that contain a mix of genetic information from each parental strand. There are 3 main forms of genetic recombination. i. Homologous recombination ii. Site-specific recombination iii. Transposition www.examville.com
How does homologous recombination differ from crossing over?
There does not seem to be much difference. Recombination introduces genetic diversity. Single Crossing over results in genetic recombination. Double crossovers may or may not result in genetic recombination.
What are moving fragments of DNA from one organism and inserting them into another organism?
DNA recombination.
Removing a section of DNA to be used for recombination is called?
Cleaving.
An example sentence using the word recombination in it?
The word "recombination" is a noun. An example of a sentence using the word would be: She understood that DNA recombination involved the exchange of genetic material.
Why is recombination DNA a new form of DNA?
Recombinant DNA is a new form of DNA because it is created via introduction of the relevant DNA into the existing organismal DNA.

What change in the DNA is called a?
A Change in a DNA molecule is called a Mutation. This could have anything from no effect whatsoever, to causing a catastrophic disease (such as Sickle Cell Anaemia) to death.
