Transgenic Plants And Animals Examples

Genetically modified salmon was the first transgenic animal for food production.

Transgenic plants and animals examples. The transgenic plants thus produced show expression of foreign genes resulting in a higher level of herbicide tolerance. The plants which are genetically engineered to carry desirable traits like disease resistance insect resistance herbicide resistance are called as transgenic plants. For example Bt cotton contains a gene from the bacteria Bacillus thuringiensis and is thus considered to be a transgenic plant.

What are transgenic plants explain with any two examples. However transgenic mice expressing the human gene for the polio virus receptor. So normal mice cannot serve as an inexpensive easily-manipulated model for studying the disease.

Examples of transgenic animals. Dolly the sheep was the first mammal to be cloned from an adult cell. This chapter aims to discuss genetically modified animals their potential to explicate biological processes related to pharmacological research and their functional genomics.

These animals and methods include. Sheep goats pigs cows rabbits rats mice fish insects parasites and even humans have previously been used in this modification process. Examples of Transgenic Animals.

In 1952 cloning of frogs through nuclear transfer. 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 crops eg cotton rice maize potato tomato brinjal cauliflowers cabbage etc The most notable example is Bt cotton which contain cryAc gene that is resistant to a notorious insect pest bollworm Helicoperpa armigera.

The foreign gene is constructed using recombinant DNA methodology. 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 chromosome. Thro 2004 emphasized that there are conflicting views about the idea.
