Species Transgenic Animals Examples

In this the udder cells from a 6-year-old Finn Dorset white sheep were injected into an unfertilized egg from a Scottish Blackface ewe which had its nucleus removed.

Species transgenic animals examples. Transgenic animals are those that have been genetically modified. One notable example of this is the injection of material from a certain species of jellyfish into other creatures. The major types of transgenic animals are listed with examples of each.

Transgenic animals whose genome has been altered to produce pharmaceuticals offer some advantages over traditional methods of drug production. Sheep goats pigs cows rabbits rats mice fish insects parasites and even humans have previously been used in this modification process. Dolly the sheep was the first mammal to be cloned from an adult cell.

Normal Physiology and Development. 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. 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.

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. 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. 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.

The simplest type of transgenic animals are those which have genetic material inserted into their own code for research purposes. 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. 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.

Mouse common transgenic expt. It examines one example of an application of a utilitarian approach. For example the study of complex factors involved in growth such as insulin likes growth factors.
