Species Transgenic Animals Examples

A transgenic animal is one that carries a foreign gene that has been inserted into its genome.

Species transgenic animals examples. Following are the examples of transgenic animals. For example although microorganisms such as bacteria generate many drugs sometimes drug proteins useful to humans require changes to their structure after they have been synthesized. It was created by inserting a human growth hormone gene in mouse genome.

Dolly the sheep was the first mammal to be cloned from an adult cell. An example of the replacement of higher species by lower species is the possibility to develop disease models in mice rather than using dogs or non-human primates. In the long term a reduction in the number of animals used for example to study human diseases is possible due to a greater specificity of the transgenic models developed.

Normal Physiology and Development. Similarly transgenic sheep expressing growth horm6ne may show diabetic like. It has been observed that transgenic pigs having enhanced growth rate and efficient feed conversion exhibit reduced reproductive performance and may suffer from arthritis and dermatitis etc.

The foreign gene is constructed using. Species transgenic animals examples. A transgenic animal is where you take a piece of DNA thats not normally found in that animal and place it back among its normal chromosomes.

For example the insertion of a single human gene into a mouse would not be expected to produce an observable human characteristic. To date transgenic research has shown that it is unlikely that the insertion of a single gene from one species into an animal of another species would change the animals phenotype. GloFish are zebrafish that have been given genes that make them glow.

In the interest of educating the public about transgenic animals and determining their effect on society the methods of creating transgenic animals is discussed. In addition to the gene itself the DNA usually includes other sequences to enable it to be incorporated into the DNA of the host and to be expressed correctly by the cells of the host. First transgenic animal was a Supermouse created by Ralph Brinster U Pennsylvania and Richard Palmiter University of Washington in 1982.
