Transgenic Plants Animals Definition. Recombinant dna methodology is used to construct the gene that is intended to express desirable qualities during the growth and development of the recipient animal. The transgenic animals are created because of the benefits they provide to the man.
The exact definition of a genetically modified organism and what constitutes genetic engineering varies, with the most common being an organism altered in a way that does not occur naturally by mating and/or natural recombination. A transgenic animal is one whose genome has been altered by the transfer of a gene or genes from another species or breed. Transgenic animals, with overexpression or activation of oncogenes and genes implicated to be important in human cancer, have been shown to produce mammary carcinomas that recapitulate human brca.
These remnants of genetic material are harmful to human health that can cause allergens.
Foreign genes are inserted into the germ line of the animal, so it can be transmitted to the progeny. An animal that has had a new dna sequence introduced into its germ line by insertion into a fertilized egg or an early embryo. Sheep, goats, pigs, cows, rabbits, rats, mice, fish, insects, parasites and even humans have previously been used in this modification process. They are characterized for being foods whose seeds have been modified genetically, so that these have not appeared of natural form, but that have.
