Production Of Transgenic Animals Notes

Transgenic organisms are organisms that are injected with foreign DNA.

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. 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. Milk as the Medium of Protein Production.

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. The first transgenic animal was produced is mice by injecting DNA to mouse embryos then implanting the embryos in female mice. Applications of Genetically modified animals.

Due to the controversial concept of cloning and scientific testing on animals there are many questions that revolve around this topic. 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. Studying gene function.

Trans-genesis is important for improving the quality and quantity of milk meat eggs and wool production besides creating drug resistant animals. The medical and biotechnological uses of animal cloning are almost innumerable as many diseases have been eradicated thanks to the production of these transgenic animals. Transgenic animals can be used to produce valuable products.

After injecting the DNA the embryo is implanted into the uterus of receptive females. A transgenic animal is an animal in which one or more genes have been introduced into its nonreproductive cells. Methods to produce transgenic animals.

The first transgenic animal was produced in 1983 when genes for human growth hormone were introduced into mice. The animals used for transgenic purpose naturally carry the mechanism needed to produce complex protein. The foreign gene is constructed using recombinant DNA methodology.
