perÂ·iÂ·naÂ·tal. adj. Of, relating to, or being the period around childbirth, especially the five months before and one month after birth: perinatal mortality; perinatal care.
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....
The Bt gene with the resistance gene attached is inserted into plant cells. At this point, scientists must determine which plant cells have successfully received the Bt gene and are now transformed. Any plant cell that has the Bt gene must also have the resistance gene that was attached to it.he modified plants produce the same lethal Bt protein produced by Bt bacteria because the plants now have the same gene. Research to transfer insect resistance genes from Bt to crop plants is well under way. Corn, cotton, and potatoes are three of the many commercial crops targeted for Bt insect resistance.
