Question

Write the information of any three genetically modified crops

Answer 1

Herbicide tolerance...

Genetically modified crops engineered to resist herbicides are now more available than conventionally bred resistant varieties.They comprised 83% of the total GM crop area, equating to just under 8% of the arable landworldwide. Approval has been granted to grow crops engineered to be resistant to the herbicides 2,4-dichlorophenoxyacetic acid,dicamba, glufosinate glyphosate,sulfonylurea, nastran   isoxafkutole Most herbicide resistant GM crops have been engineered for glyphosate tolerance, in the USA 93% of soybeans and most of the GM maize grown is glyphosate tolerant

insect resistance

Most currently available genes used to engineer insect resistance come from the  bacillus thuringienus bacterium. Most are in the form of Delta exaltation known as cry proteins, while a few use the genes that encode for vegetative insecticidal Insect resistant crops target various species of (beetles) and  lepidopterna(moths). The only gene commercially used to provide insect protection that does not originate from B. thuringiensis is the cowpeatryspin inhabited CpTI was first approved for use cotton in 1999 and is currently undergoing trials in rice..

stacked...

Many varieties of GM crops contain more than one resistance gene. This could be in the form of multiple insect resistant genes, multiple herbicide tolerance genes or a combination of the herbicide and insect resistant genes.  smart tax  is a brand of GM maize that has eight different genes added to it, making it resistant to two types of herbicides and toxic to six different species of insects...

Answer 2

HERE IS YOUR ANSWER.

DNA recombinant technology refers transfer of genes from one organism to another so as to modify the latter. They are called genetically modified organisms or transgenic organisms. Such transgenic food plants are called genetically modified food. Bt cotton is a genetically modified crop which carries bacterial genes that protects plants from insects. By stands for the bacterium back plus thuringiensis whose games are used by transgenic crops such as cotton, rice, maize, potato, tomato, brinjal, cauliflower, cabbage etc. to get protection from the insects and pests.
