Transgenic Plants And Animals Examples
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.
Transgenic plants and animals examples. Their examples uses Importance and methods used to produce them. 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.
Normal mice cannot be infected with polio virus. Examples of transgenic animals. Bt cotton was adopted for mass cultivation in India in year 2002.
New Zealanders need to weigh up the risks and benefits associated with transgenic cows and decide what they consider to be acceptable. 1994 1st genetically modified crop approved for sale in US. This chapter aims to discuss genetically modified animals their potential to explicate biological processes related to pharmacological research and their functional genomics.
Mice however are the most popularly tested animals in genetic modification studies. These animals and methods include. They lack the cell-surface molecule that in humans serves as the receptor for the virus.
And then when that mouse is born it can transmit that extra piece of DNA to its offspring. History 1982 1st transgenic plant produced which is an antibiotic resistance tobacco plant. Some important examples of transgenic animals are as follows.
Major concerns on transgenic plants and animals The production of transgenic plants and animals has faced several concerns among conservatives in Europe America and almost every corners of the globe. 1984 1st successful plant genetic engineering experiments using caulimovirus vector. 1994 first mammal cloned from a somatic cell nuclear transfer.
