Protein Gene:- The gene of interest which codes for a particular protein in inserted in the genome of the corn. Bt genes produce Cry proteins in the corn. Promoter:- Along with the Bt gene, a promoter is also inserted into the corn.The function of the promoter is to control the Cry protein and it also sees that how much protein is produced by the plant.rticle Summary: Bt corn is a genetically modified crop. A protein is inserted into the plant's genome which is extracted from the bacterium Bacillus thuringiensis. This bacterium increases the soil fertility. When insects eat this plant, they get starved and die as a result....
About Bt corn Monsanto's GM Bt corn is equipped with a gene from soil bacteria called Bt or Bacillus thuringiensis. This produces the Bt-toxin in the corn. The pesticide breaks open the stomach of certain insects and kills them. This Bt corn was introduced into the food supply in the late 1990's and problems have been occurring ever since. Monsanto and the EPA swore that the genetically engineered corn would only harm insects. They stated that the Bt-toxin produced inside the plant would be completely destroyed in the human digestive system. They said it would not have any impact on the health of consumers.
