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....
Aa Aa Aa. Transposable elements (TEs), also known as jumping genes  or transposons, are sequences of DNA that move (or jump) from one location in the genome to another.Maize geneticist Barbara McClintock discovered TEs in the 1940s, and for decades thereafter, most scientists dismissed transposons as useless or junk DNA.arbara McClintock and the Discovery of Jumping Genes (Transposons). Discovery of DNA as the Hereditary Material using Streptococcus pneumoniae. Discovery of DNA Structure and Function: Watson and Crick. Isolating Hereditary Material: Frederick Griffith, Oswald Avery, Alfred Hershey, and Martha Chase.
