Production Of Transgenic Animals Notes

The transgenic animals are created because of the benefits they provide to the man.

Production of transgenic animals notes. Benefits of Transgenic Animals The benefits of these animals to human welfare can be grouped into areas. Transgenic organisms are organisms that are injected with foreign DNA. A transgenic animal is an animal in which one or more genes have been introduced into its nonreproductive cells.

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. One favoured method involves the inoculation of the DNA into the pronucleus of a fertilised ovum followed by implantation into pseudo pregnant females.

Animals that have had their DNA manipulated to possess and express a foreign gene are known as transgenic animals. Due to the controversial concept of cloning and scientific testing on animals there are many questions that revolve around this topic. 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.

Advantages of Transgenic Animals. 43 Creation of the transgenic animal A number of methods are currently in use for the creation of transgenic animals. The cells are then incorporated into an embryo at the blastocyst stage of development.

To yield industrial as well as consumer product To research human diseases To produce pharmaceutical products and tissue for implantation. Agricultural Applications a Breeding Farmers have always used selective breeding to produce animals that exhibit desired traits eg. PowerPoint PPT presentation.

Applications Of 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. The animals used for transgenic purpose naturally carry the mechanism needed to produce complex protein.
