Production Of Transgenic Animals Notes

Transgenic animals are being used to study gene mechanism and function to adapt pig organs to be transferred to humans to prepare recombinant pharmaceutical proteins in milk and egg white and to improve breeding and food production.

Production of transgenic animals notes. Transgenic animals have the potential of agricultural applications like improved growth rate and carcass composition improved resistance to disease increased milk. Genetically modified animals are proving ever more vital in. Animals that have had their DNA manipulated to possess and express a foreign gene are known as transgenic animals.

The transgenic expression is not only used to breed animals which have specific traits but also to breed animals that are lacking specific genes This technique is called as knockout or gene. The development of transgenic animals has been part of biotechnology research which has been expanding rapidly. Due to the controversial concept of cloning and scientific testing on animals there are many questions that revolve around this topic.

Example- Transgenic rats rabbits pigs sheep etc. Transgenic animals produced with the purpose of producing better and good quality breed increased in milk yield as well as to produce organs to meet the demand for organ transplantation. Biotechnology for Sustainable Agriculture 2018.

Applications Of Transgenic Animals. Many procedures have been developed to increase the efficiency of this generally inefficient process. The foreign genes must be transmitted through the germ line so that every cell including germ cells of the animal contains the same modified genetic material.

Methods to produce transgenic animals. The transgenic animals are created because of the benefits they provide to the man. Transgenic mice are developed by injecting DNA into the oocytes or 1-2 celled embryos taken from female mice.

The foreign gene is constructed using recombinant DNA methodology. Milk as the Medium of Protein Production. The cells are then incorporated into an embryo at the blastocyst stage of development.
