Transgenic Animals Are Those Which Have Foreign Dna In

This gene gives an extra character to that animal.

Transgenic animals are those which have foreign dna in. Transgenic organism is one that has become transformed following the introduction of novel genes into its genome. In addition to the gene itself the DNA usually includes other sequences to enable it to be incorporated into the DNA of the host and to be expressed correctly by the cells of the host. Transgenic animals have had a foreign gene inserted into their genome.

Such animals are most commonly created by the microinjection of dna into the pronuclei of a fertilised egg which is subsequently implanted into the oviduct of a pseudopregnant surrogate mother. Transgenic animals are the ones whose DNA has been manipulated in such a way that they can possess and express an extra foreign gene. A transgenic animal is one that carries a foreign gene that has been deliberately inserted into its genome.

Theoretically all living beings can be genetically manipulated. Foreign DNA in all its cells. Transgenesis is the phenomenon in which a f oreign gene with desired characteristics is introduced into the genome of the target animal.

Animals usually are made transgenic by having a small sequence of foreign DNA injected into a fertilized egg or developing embryo. The establishment of stable transgenic animals implies that the foreign DNA is present in gametes or one-cell embryos to allow its transmission to progeny. Foreign DNA in all their cells.

In addition to the gene itself the DNA usually includes other sequences to enable it to be incorporated into the DNA of the host and. Foreign DNA in all its cells. Now adays it is possible to alter genes of plants bacteria or viruses to get.

The foreign gene is constructed using recombinant DNA methodology. The animals which carry foreign genes are called transgenic animals. So the correct answer is Foreign DNA.
