Transgenic Plants And Animals Examples
Environmental Protection Agency 1996 1st genetically modified.
Transgenic plants and animals examples. Bt cotton was adopted for mass cultivation in India in year 2002. For example Bt cotton contains a gene from the bacteria Bacillus thuringiensis and is thus considered to be a transgenic plant. The foreign gene is constructed using recombinant DNA methodology.
The future of transgenic cow research in New Zealand depends upon funding regulations and public opinion. Examples of transgenic species salmon with bovine growth hormones that grows faster and produces more meat potato plants with pea genes that enhance the potatos resistance Enzymatic joining of dna strands. A transgenic animal is one that carries a foreign gene that has been inserted into its genome.
Transgenic organisms are those that undergo genetic engineering. Normal mice cannot be infected with polio virus. 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.
However transgenic mice expressing the human gene for the polio virus receptor. 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. And then when that mouse is born it can transmit that extra piece of DNA to its offspring.
Examples of Transgenic Animals. Gene transfers have been successful in various fish such as common carp rainbow trout Atlantic salmon catfish goldfish zebra-fish etc. History 1982 1st transgenic plant produced which is an antibiotic resistance tobacco plant.
1995 1st pesticide producing crop Bt Potato was approved by US. 1994 first mammal cloned from a somatic cell nuclear transfer. Their examples uses Importance and methods used to produce them.
