Transgenesis

Transgenesis

Transgenesis is the set of techniques to transfer one or more genes from one organism said donor organism to a recipient organism called recipient organism, or even host organism, to obtain a genetically modified organism. To transfer this gene from one organism to another it passes through a vector often designed from the genetic program of a bacterium or virus.

So that transgenesis be possible, certain conditions are essential. First you should know that transgenics is made possible through the universality of genetic code. We must therefore ensure that the gene is introduced into the recipient organism fits well into the genome so that it can express. It must also be transmitted to the offspring.

To be successful transgenesis requires:

- Penetration of the transgene in the target cells

- son intégration dans le génome

- Its ability to expressing in the cells (protein production)

- And finally the possibility of obtaining the regeneration of whole individuals from genetically modified cells.
