Answer:
A gene had been isolated from the Bacterium Bacillus Thuringiensis and integrated with the gene of cotton. Due to this, the toxin which is fatal for bollworm was produced in leaves and bolls of cotton. If bollworm feeds on leaves, the toxin destroys its alimentary canal and the bollworm dies.
