Species Transgenic Animals Examples

GloFish are zebrafish that have been given genes that make them glow.

Species transgenic animals examples. 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. Following are the examples of transgenic animals. A transgenic animal is one that carries a foreign gene that has been inserted into its genome.

The simplest type of transgenic animals are those which have genetic material inserted into their own code for research purposes. 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. For example the insertion of a single human gene into a mouse would not be expected to produce an observable human characteristic.

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. Sheep goats pigs cows rabbits rats mice fish insects parasites and even humans have previously been used in this modification process. It examines one example of an application of a utilitarian approach.

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. Transgenic animals can be specifically designed to allow the study of how genes are regulated and how they affect the normal functioning of the body and its development. The foreign gene is constructed using recombinant DNA methodology.

One notable example of this is the injection of material from a certain species of jellyfish into other creatures. 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. Mouse common transgenic expt.

For example the study of complex factors involved in growth such as insulin likes growth factors. Organisms that have altered genomes are Transgenic chickens are now able to synthesize human proteins in the white of their eggs. 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.
