When a gene of interest is inserted in some other organism to see particular traits, it is necessary to insert some additional components also, so that the function of the desired gene can be observed properly. When we talk about the Bt corn, then the gene of interest is inserted in the following way.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....
