Question

One of the main objectives of biotechnology is to minimise the use of insecticides on cultivated crops. Explain with the help of a suitable example, how insect-resistant crops have been developed using techniques of biotechnology.

Answer 1

PLEASE MARK MY ANSWER AS BRAINLIST

Bt cotton is a genetically modified organism (GMO) or genetically modified pest resistant plant cotton variety, which produces an insecticide to combat bollworm.

MECHANISM :-

The Bt toxin dissolve in the high pH insect gut and become active. The toxins then attack the gut cells of the insect, punching holes in the lining. The Bt spores spills out of the gut and germinate in the insect causing death within a couple days.

Answer 2

Objectives of Biotechnology

Explanation:

• Creepy crawlies may create protection from a harvest resistance regardless of how it was created.
• The yield resistance may be a compound or organic specialist, a quality as of now in the harvest species and moved to business plants by customary plant-reproducing techniques or a quality presented by recombinant DNA innovation.
• impervious to both lepidopteran and coleopteran hatchlings (root worms) have gotten generally utilized in worldwide farming and have prompted decreases in pesticide utilization and lower production costs
