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....
In 1979, scientists at Genentech produced human growth hormone by inserting DNA coding for human growth hormone into a plasmid that was implanted in Escherichia coli bacteria. The gene that was inserted into the plasmid was created by reverse transcription of the mRNA found in pituitary glands to complementary DNA.rowth hormone. Prior to the use of recombinant DNA technology to modify bacteria to produce human growth hormone, the hormone was manufactured by extraction from the pituitary glands of cadavers, as animal growth hormones have no therapeutic value in humans.
