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.

Production of transgenic animals notes. Theses mechanism is absent in cell culture. The animals used for transgenic purpose naturally carry the mechanism needed to produce complex protein. 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. Agricultural Applications a Breeding Farmers have always used selective breeding to produce animals that exhibit desired traits eg. In addition to the gene itself the DNA usually includes other sequences to enable it to be incorporated into the DNA of the host and to be expressed correctly by the cells of the host.

The first transgenic animal was produced is mice by injecting DNA to mouse embryos then implanting the embryos in female mice. Animals that have had their DNA manipulated to possess and express a foreign gene are known as transgenic animals. Transgenic animals are created-To study how genes are regulated and how they affect the normal functions of the body and its development.

Then they are inserted into a blastocyst and implanted into a hosts uterus to grow normally. The first transgenic animal was produced in 1983 when genes for human growth hormone were introduced into mice. Let us discuss a few of them here.

Studying gene function. ES cells are obtained from the inner cell mass of a blastocyst. Benefits of Transgenic Animals The benefits of these animals to human welfare can be grouped into areas.

Many procedures have been developed to increase the efficiency of this generally inefficient process. Transgenic mice are developed by injecting DNA into the oocytes or 1-2 celled embryos taken from female mice. Transgenic animal technologies have come a long way since the creation of the first transgenic mouse in 1974 Transgenic Mouse 2005.
