History of transgenic animals ppt. The transgenic technology is one of an important tool to meet the future challenges for increased animals production. Transgenic invertebrate species include some. 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.
The transgenic plants thus produced show expression of foreign genes resulting in a higher level of herbicide tolerance. 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. These include reproductive science genetics and molecular biology and micromanipulation and microscopy equipment.

The gene introduces by transfection is called transgene. 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.
DEFINITION An individual in which a gene or genes were introduced by one or other technique of transfection to the genome of a animal is called transgenic animals. Transgenic vertebrates have been developed in species with both scientiﬁc and commercial value including ﬁsh amphibians birds and mammals. 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.
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. The transgenic animals are created because of the benefits they provide to the man. Transgenic animals are certainly a good turn of events since transgenic technology holds great potential in many fields.
Sheep goats pigs cows rabbits rats mice fish insects parasites and even humans have previously been used in this modification process. Transgenic animals have been produced in a variety of species Table 1. The production of transgenic animals has focused mainly on producing models eg the mouse for basic and medical research.
