Production Of Transgenic Animals Notes

43 Creation of the transgenic animal A number of methods are currently in use for the creation of transgenic animals.

Production of transgenic animals notes. Many procedures have been developed to increase the efficiency of this generally inefficient process. ES cells are obtained from the inner cell mass of a blastocyst. PowerPoint PPT presentation.

The first transgenic animal was produced is mice by injecting DNA to mouse embryos then implanting the embryos in female mice. Transgenic animals can be used to produce valuable products. 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 three main ways of producing transgenic animals are pronuclear manipulation embryonic stem ES cell manipulation and. The foreign gene is constructed using recombinant DNA methodology. Agricultural Applications a Breeding Farmers have always used selective breeding to produce animals that exhibit desired traits eg.

The first transgenic animal was produced in 1983 when genes for human growth hormone were introduced into mice. Trans-genesis is important for improving the quality and quantity of milk meat eggs and wool production besides creating drug resistant animals. Transgenic animals are created-To study how genes are regulated and how they affect the normal functions of the body and its development.

Biotechnology for Sustainable Agriculture 2018. To yield industrial as well as consumer product To research human diseases To produce pharmaceutical products and tissue for implantation. Applications of Genetically modified animals.

One favoured method involves the inoculation of the DNA into the pronucleus of a fertilised ovum followed by implantation into pseudo pregnant females. Milk is the secretion of mammary glands that can be collected frequently without causing any harm to the animal. Benefits of Transgenic Animals The benefits of these animals to human welfare can be grouped into areas.
