Genetically modified genetically plants pass through diverse domestication from wild species and many generations of selection by humans for desirable traits. These genetically modified genetically crops are diversely produced in different industries to decrease the attack of pests by transferring different combinations of genes through advanced technologies. The gene of interest is inserted into the crop's genome using a vector that exhibits the biological carrier genes. Bacillus thuringiensis (Bt) corn is the genetically modified corn that produces most of essential proteins necessary for human body also secrete toxic to certain insect pests. Genetically engineered cotton is the most evolutionary step to replace the traditionally used methods for production of cotton. Genetically engineered canola has been produced by inserting through high technology methods. Protein samples can be obtained from genetically modified crops can be resolved with the one-dimensional SDS-gel electrophoresis. Genetically engineered crops have many advantages, and the benefits of being able to use herbicides that would cause unacceptable phytotoxicity to a crop are clear.
