Transgenic Animal Technology Ppt

Transgenic animals lecture 35.

Transgenic animal technology ppt. 62 Recombinant DNA Technology. Recombinant DNA technology is the ability to combine DNA molecules from different sources into the one molecule. 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 transgenesthe foreign genes must be transmitted through the germ line so that every cell including germ cells of the.

When we think of genetic engineering most of us probably think of transgenics. This technology was extended into animals shortly after 1974 with the first transgenic animal a mouse containing SV-40 viral DNA fragments Jaenisch and Mintz 1974. Transgenic animal technologies and the ability to introduce functional genes into animals have revolutionized our ability to address complex biomedical and biological questions.

By DAMARIS BENNY DANIEL II Msc. The foreign gene is constructed using recombinant DNA methodology. The transgenic technology is one of an important tool to meet the future challenges for increased animals production.

The emergence of transgenic technology has widened the scope of development in case of farm animals and the advent of new molecular biology techniques has paved way by giving a new dimension to animal breeding. Numerous transgenic fish have been developed using a variety of transgenes methods and species since the first transgenic fish were produced in China in 1985 Zhu et al 1985 reviewed by Chen and Powers 1990 Fletcher and Davies 1991 Maclean 1998 Hackett 1993 Dunham 2011Since that time transgenic gene knockout technology Thresher et al 2009 Wong and Van. Thus the abilities or the phenotype of the organism or the proteins it produces can be.

DEFINITION An individual in which a gene or genes were introduced by one or other technique of transfection to the genome of a animal is called transgenic animals. In terms of commercially important livestock species work has revolved around specialized non-agricultural purposes such as pharmaceutical production and xenotransplantation and to a lesser extent applied agricultural purposes to improve animal. Transgenesis in Mice Retroviral Vector Efficient mechanism of transgene integration Transfer of genes 8 kb possible random insertion of the transgene.

Transgenic animals or plants are those that have. 11 These and chronic models for the evaluation of transgenic animals can express HIV-1 proteins. Khan Medical Biotechnology Divis ion School of Biosciences and Technology VI T University Vellore-632014 Tamil Nadu India.
