What is transgenic organism?
Transgenic Organisms. Modern genetic technology can be used to modify the genomes of living organisms. This process is also known as “genetic engineering.” Genes of one species can be modified, or genes can be transplanted from one species to another. Genetic engineering is made possible by recombinant DNA technology.

What are the applications of transgenic animals?
Applications of animal transgenesis may be divided into three major categories: (i) to obtain information on gene function and regulation as well as on human diseases, (ii) to obtain high value products (recombinant pharmaceutical proteins and xeno-organs for humans) to be used for human therapy, and (iii) to improve animal products for human consumption. All these applications are directly or not related to human health. Animal transgenesis started in 1980. Important improvement of the methods has been made and are still being achieved to reduce cost as well as killing of animals and to improve the relevance of the models. This includes gene transfer and design of reliable vectors for transgene expression. This review describes the state of the art of animal transgenesis from a technical point of view. It also reports some of the applications in the medical field based on the use of transgenic animal models. The advance in the generation of pigs to be used as the source of organs for patients and in the preparation of pharmaceutical proteins from milk and other possible biological fluids from transgenic animals is described. The projects in course aiming at improving animal production by transgenesis are also depicted. Some the specific biosafety and bioethical problems raised by the different applications of transgenesis, including consumption of transgenic animal products are discussed.

Human gene therapy is the process in which by using the technique of gene therapy in which healthy genes are inserted in the person's body in place of defected genes. Defected genes do not function properly and cause diseases in the body. Plasmids and vectors are used to carry healthy genes. transgenic animals could play vital role in the treatment of almost 5000 genetic disorders. For example the scientists of Finland have developed a calf which carries a gene. This gene is responsible for making a substance which promotes the growth of red blood cells in humans.

Breeding:-. It is the culture of all farmers to breed animals selectively so that healthy animals can be obtained that have the traits required by the farmers, for example, increased amount of milk and healthy meat. Though traditional breeding is also common but it gives slow results as it is a time consuming method.
