EASY
Which part of the tobacco plant is infected by Meloidogyne incognita?
EASY
Golden rice is a genetically modified crop plant where the incorporated gene is meant for the biosynthesis of
MEDIUM

Assertion (A) : Transgenic Golden Rice is rich in Vitamin A and prevents blindness.

Reason (R) : It is obtained from "Taiwan"

EASY
H. Boyer & S. Cohen are famous for their research work on
MEDIUM

Assertion (A): Bt toxin exists as inactive prototoxin but once an insect ingests the inactive toxin, it is converted into an active form of toxin.

Reason (R):  Protoxin gets activated in insect gut due to the acidic pH in the gut, which solubilises the protein crystals.

The correct answer is:

EASY
On whom was the world’s first successful skull-scalp transplant done?
MEDIUM
Assertion (A): cry is insect group specific gene of Bt cotton
Reason (R):  cry IAc and cry IIAb controls the cotton boll worms
MEDIUM

Assertion A: In Bt cotton B. thuringiensis produces a toxic insecticidal crystalline protein which destroys bollworms.

Reason R: B. thuringiensis produces this toxic protein in an inactive form, but when an insect ingests this inactive protein, it is converted into active form of toxin due to the alkaline pH of gut which solubilises the crystals, which is responsible for the death of bollworm.

EASY
In Bt cotton, the Bt toxin present in plant tissue as pro-toxin is converted into active toxin due to:
MEDIUM

A) Change the phenotype of host-organism by genetic engineering
B) Chemical engineering process of vaccine production by tissue culture
C) Manufacture of specific products from eukaryotic cells in bioreactors
D) Altering the chemistry of genetic material by tissue culture
