Question

What is recombination? Discuss the applications of recombination from the point of view of genetic engineering?

Answer 1

Recombination, in genetics, is the primary mechanism through which variation is introduced into populations. Recombination takes place during meiosis, when maternal and paternal genes are regrouped within the formation of gametes (sex cells).

Complete answer:
The rearrangement of genetic material, especially by crossing over in chromosomes or by the artificial joining of segments of DNA from different organisms is known as recombination. This may happen naturally during meiosis. This may even be artificially induced through gene-splicing . gene-splicing has been applied in creating recombination for various species to provide useful products for humans. For example; Bt cotton and Bt brinjal are produced through gene-splicing . Some vaccines are also being produced through this process, e.g. hepatitis-B vaccine.
Genetic engineering, the synthetic manipulation, modification, and recombination of DNA or other macromolecule molecules so on switch an organism or population of organisms.
The term gene-splicing initially mentioned various techniques used for the modification or manipulation of organisms through the processes of heredity and reproduction. As such, the term embraced both artificial selection and each one the interventions of biomedical techniques, among them AIl, in vitro fertilization (e.g.test-tube babies), cloning, and gene manipulation. within the latter a neighborhood of the 20th century, however, the term came to refer more specifically to methods of recombinant desoxyribonucleic acid technology (or gene cloning), during which DNA molecules from two or more sources are combined either within cells or in vitro and are then inserted into host organisms during which they're able to propagate.

Note:
Recombinant deoxyribonucleic acid technology (RDT) is used to make microbes, plants, and animals that carry genes from other species. RDT is often utilized as a diagnostic technique of human genetic disease.
