Transgenic Animals Examples Ppt

Have been used as experimental animals for production of transgenic fish.

Transgenic animals examples ppt. 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. Foreign genes are inserted into the germ line of the animal so it can be transmitted to the progeny. This lecture states some mechanisms to develop healthy transgenic animals.

A transgenic animal is one that carries a foreign gene that has been deliberately inserted into its genome. The production of transgenic animals has focused mainly on producing models eg the mouse for basic and medical research. Then common misconceptions will be addressed and the ethics of transgenic animal creation will be discussed.

Recombinant DNA methodology is used to construct the gene that is intended to express desirable qualities during the growth and development of the recipient animal. Organisms containing integrated sequences of cloned DNA transgenes transferred using techniques of genetic engineering to include those of gene transfer and gene substitution are called transgenic animals. Mehendale in Encyclopedia of Toxicology Third Edition 2014 Abstract.

Theyll give your presentations a professional memorable appearance - the kind of sophisticated look that. Do not express key foreign antigens. 11 These and chronic models for the evaluation of transgenic animals can express HIV-1 proteins.

Depending on the purpose of the transgenic fish studies the embryos of some fish species are better suited for gene transfer studies than the others. Gene transfers have been successful in various fish such as common carp rainbow trout Atlantic salmon catfish goldfish zebra-fish etc. Organisms that have altered genomes are Transgenic chickens are now able to synthesize human proteins in the white of their eggs.

Transgenesis is the process by which mixing up of genes takes place. Following are the examples of transgenic animals. This project details transgenic animal technology applications ethics and legalities as an example of technologys impact on society.
