Production Of Transgenic Animals Notes

Trans-genesis is important for improving the quality and quantity of milk meat eggs and wool production besides creating drug resistant animals.

Production of transgenic animals notes. Animals that have had their DNA manipulated to possess and express a foreign gene are known as transgenic animals. Transgenic animals can be created by manipulating embryonic stem cells. Theses mechanism is absent in cell culture.

There are many ways to produce transgenic animals. 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. One favoured method involves the inoculation of the DNA into the pronucleus of a fertilised ovum followed by implantation into pseudo pregnant females.

Agricultural Applications a Breeding Farmers have always used selective breeding to produce animals that exhibit desired traits eg. 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 animals are created because of the benefits they provide to the man.

PowerPoint PPT presentation. Transgenic animals have the potential of agricultural applications like improved growth rate and carcass composition improved resistance to disease increased milk. To yield industrial as well as consumer product To research human diseases To produce pharmaceutical products and tissue for implantation.

Milk as the Medium of Protein Production. Due to the controversial concept of cloning and scientific testing on animals there are many questions that revolve around this topic. A transgenic animal is one that carries a foreign gene that has been deliberately inserted into its genome.

The first transgenic animal was produced is mice by injecting DNA to mouse embryos then implanting the embryos in female mice. Studying gene function. Let us discuss a few of them here.
