Species Transgenic Animals Examples
Sheep goats pigs cows rabbits rats mice fish insects parasites and even humans have previously been used in this modification process.
Species transgenic animals examples. Theoretically all living beings can be genetically manipulated. 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. 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.
Dolly the sheep was the first mammal to be cloned from an adult cell. Examples of Transgenic Animals. It examines one example of an application of a utilitarian approach.
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. For example the study of complex factors involved in growth such as insulin likes growth factors. C There may be high mortality rate and other deleterious effects on animals used by researchers to create transgenic breeds.
The simplest type of transgenic animals are those which have genetic material inserted into their own code for research purposes. 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. 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.
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. In the interest of educating the public about transgenic animals and determining their effect on society the methods of creating transgenic animals is discussed. Transgenic animals whose genome has been altered to produce pharmaceuticals offer some advantages over traditional methods of drug production.
Other animals include pig goat cow sheep fish etc. The foreign gene is constructed using recombinant DNA methodology. Organisms that have altered genomes are Transgenic chickens are now able to synthesize human proteins in the white of their eggs.
