Production Of Transgenic Animals Notes

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.

Production of transgenic animals notes. A transgenic animal is an animal in which one or more genes have been introduced into its nonreproductive cells. There are many ways to produce transgenic animals. Let us discuss a few of them here.

The cells are then incorporated into an embryo at the blastocyst stage of development. Applications of Genetically modified animals. Then they are inserted into a blastocyst and implanted into a hosts uterus to grow normally.

The development of transgenic animals has been part of biotechnology research which has been expanding rapidly. Methods to produce transgenic animals. A Gene requires certain cellular mechanism to help for the production of protein.

Example- Transgenic rats rabbits pigs sheep etc. Studying gene function. Microinjection blastocyst injection and using a retrovirus Nuclear transfers Artificial chromosomes for gene transfer PRODUCTION OF TRANSGENIC ANIMALS THE METHODOLOGY.

Applications Of Transgenic Animals. Milk as the Medium of Protein Production. Transgenic animals have the potential of agricultural applications like improved growth rate and carcass composition improved resistance to disease increased milk.

The main principle in the production of transgenic animals is the introduction of a foreign gene or genes into an animal the inserted genes are called transgenes. Transgenic animals are being used to study gene mechanism and function to adapt pig organs to be transferred to humans to prepare recombinant pharmaceutical proteins in milk and egg white and to improve breeding and food production. A transgenic animal is one that carries a foreign gene that has been deliberately inserted into its genome.
