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....
Scientists identify opium poppy codeine and morphine genes. A field of opium poppies in Pakistan. Scientists identify opium poppy codeine and morphine genes. Scientists have identified the two genes in opium poppies which are used to make codeine and morphine, two of the most important painkillers in a doctor's armoury. The discovery opens the door to alternative ways of making the drugs which do not involve giving over vast areas of farmland to growing the flowers.
