Question

What are the types of recombination?

Answer 1

Recombination:

1. It is the phenomenon of the exchange of genetic material between different regions of the same chromosome or different regions of two chromosomes.
2. It can be also defined as the physical breakage and rejoining of DNA molecules.

Three Types of recombination:

1. Homologous recombination: The exchange of genetic material between two homologous chromosomes (having a similar size and the same number of genes) during meiosis is called homologous recombination.
2. Non-homologous recombination: The exchange of genetic material between non-homologous chromosomes (no homology between two chromosomes) is called non-homologous recombination or crossing over.
3. Site-specific recombination: The type of recombination in which DNA is cut from a specific site with the help of restriction endonucleases enzymes and insertion of the desired interest of DNA is called Recombinant DNA Technology.
