Species Transgenic Animals Examples

Transgenic animals whose genome has been altered to produce pharmaceuticals offer some advantages over traditional methods of drug production.

Species transgenic animals examples. 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. 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. This paper examines questions of where ethical issues about transgenic animals stem from how we make ethical decisions and whether ethical issues concerning transgenic animal production are different from those in the production of n on-transgenic animals.

The foreign gene is constructed using. For example the insertion of a single human gene into a mouse would not be expected to produce an observable human characteristic. Mouse common transgenic expt.

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. 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 that carry genetically engineered genes from other species have great potential to improve human welfare.

Normal Physiology and Development. The major types of transgenic animals are listed with examples of each. Sheep goats pigs cows rabbits rats mice fish insects parasites and even humans have previously been used in this modification process.

Transgenic plants and animals Transgenic plants are plants that have been genetically engineered a breeding approach that uses recombinant DNA techniques to create plants with new characteristics. First transgenic animal was a Supermouse created by Ralph Brinster U Pennsylvania and Richard Palmiter University of Washington in 1982. Examples of Transgenic Animals.

Dolly the sheep was the first mammal to be cloned from an adult cell. One notable example of this is the injection of material from a certain species of jellyfish into other creatures. 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.
