History of transgenic animals ppt. These animals are widely used to understand gene function and protein function. The first genetically modified or ganism was a bacterium. Transgenic models are more precise in comparison to traditional animal models for example the oncomouse with its increased susceptibility to tumor development enables results for carcinogenicity studies to be obtained within a shorter time-frame thus reducing the course of tumor development in experimentally affected animals.

Organisms containing integrated sequences of cloned DNA transgenes transferred using techniques of genetic engineering to include those of gene transfer and gene substitution are called transgenic animals. Bubonic Plague in History In the late Middle Ages 13401400 Europe experienced the most deadly disease outbreak in history when the Black Death the infamous pandemic of bubonic plague hit in 1348 killing a third of the human population PPT-089-01. How Bt Cotton Was Developed About ten years ago Monsanto scientists inserted a toxin gene from the bacterium called Bt which is the nickname for Bacillus thuringiensis into cotton plants to create a caterpillar-resistant variety.

The emergence of transgenic technology has widened the scope of development in case of farm animals and the advent of new molecular biology techniques has paved way by giving a new dimension to animal breeding. In l986 they isolated a cDNA clone encoding an enzyme 5-enolpyruvyl-shikimate phosphate. Applications Of Transgenic Animals.

The transgenic plants thus produced show expression of foreign genes resulting in a higher level of herbicide tolerance. The development of transgenic animals has been part of biotechnology research which has been expanding rapidly. Then at more than a year of age during the spring of 1985 the founder and his first-generation progeny began to develop skin abnormalities and then protuberant tumors later shown to.

Transgenic mice are developed by injecting DNA into the oocytes or 1-2 celled embryos taken from female mice. In general transgenic animals are used to address three fundamentally distinct topics. The production of transgenic animals has focused mainly on producing models eg the mouse for basic and medical research.

The gene introduces by transfection is called transgene. Sheep goats pigs cows rabbits rats mice fish insects parasites and even humans have previously been used in this modification process. This project details transgenic animal technology applications ethics and legalities as an example of technologys impact on society.
