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. The development of transgenic animals has been part of biotechnology research which has been expanding rapidly. A Gene requires certain cellular mechanism to help for the production of protein. 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.

Transgenic animals are created-To study how genes are regulated and how they affect the normal functions of the body and its development. The transgenic animals are created because of the benefits they provide to the man. Transgene is incorporated into the ES cell by Microinjection By a retro virus By electroporation Transgenic stem cells are grown in vitro.

A transgenic animal is one that carries a foreign gene that has been deliberately inserted into its genome. Agricultural Applications a Breeding Farmers have always used selective breeding to produce animals that exhibit desired traits eg. 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.

Transgenic animals are used as tools in research and for the production of recombinant proteins The main applications of transgenic animals are described as follows. The three main ways of producing transgenic animals are pronuclear manipulation embryonic stem ES cell manipulation and. ES cells are obtained from the inner cell mass of a blastocyst.

Transgenic animals can be used to produce valuable products. Transgenic animals can be created by manipulating embryonic stem cells. Due to the controversial concept of cloning and scientific testing on animals there are many questions that revolve around this topic.

Benefits of Transgenic Animals The benefits of these animals to human welfare can be grouped into areas. Animals that have had their DNA manipulated to possess and express a foreign gene are known as transgenic animals. Milk is the secretion of mammary glands that can be collected frequently without causing any harm to the animal.
