Species Transgenic Animals Examples

It examines one example of an application of a utilitarian approach.

Species transgenic animals examples. Transgenic animals that carry genetically engineered genes from other species have great potential to improve human welfare. Dolly the sheep was the first mammal to be cloned from an adult cell. In the interest of educating the public about transgenic animals and determining their effect on society the methods of creating transgenic animals is discussed.

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. 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. Normal Physiology and Development.

Similarly transgenic sheep expressing growth horm6ne may show diabetic like. DNA microinjection embryonic stem cell-mediated gene transfer retrovirus-mediated gene transfer and artificial chromosome transfer are some popular methods used to produce transgenic animals. Transgenic animals whose genome has been altered to produce pharmaceuticals offer some advantages over traditional methods of drug production.

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. Examples of transgenic species Salmon with bovine growth hormones that grows faster and produces more meat Potato plants with pea genes that enhance the potatos resistance. Mouse common transgenic expt.

Transgenic animals are those that have been genetically modified. So for example you can make a transgenic by having a piece of DNA that you clone in a laboratory and inject it into a fertilized egg of a mouse embryo for example then that becomes integrated into the. 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.

One notable example of this is the injection of material from a certain species of jellyfish into other creatures. It was created by inserting a human growth hormone gene in mouse genome. Organisms that have altered genomes are Transgenic chickens are now able to synthesize human proteins in the white of their eggs.
