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....
A bacteria with the name Agrobacterium Tumefasciens has the ability to induce a kind of benign tumor growth in the plant it infects. This it achieves by inserting some genes into the DNA of the plant. In genetic engineering, the gene that is to be inserted is hooked on to the bacterial DNA.Then the recipient cells are exposed to the bacterium, so that they become infected by it.pecial techniques are used, that are of no imporance here. 2. A gene is much too small to be inserted with some kind of microsurgery. Therefore some carrier (vector) is required which takes the gene into the recipient cell and somemhow gets it inserted into the DNA of the recipient.
