Match the following lists:

The correct match is

Assertion $\left(\mathrm{A}\right):$ Bt toxin exists as inactive prototoxin but once an insect ingests the inactive toxin, it is converted into an active form of toxin.

Reason $\left(\mathrm{R}\right):$  Protoxin gets activated in insect gut due to the acidic $\mathrm{pH}$ in the gut, which solubilises the protein crystals.

The correct answer is:

Choose the correct statements on Bt cotton.
A) Inactive prototoxin activation occurs in alkaline $\mathrm{pH}$
B) Choice of Bt toxin genes is universal to all crops but specific to the targeted pest
C) Choice of Bt toxin genes are universal to pest but specific to crop
D) All strains of Bacillus thuriangensis do not produce prototoxin

Identify the correct sequence of steps that are followed in gene therapy.
A Altered virus is mixed with cells from patient
B. Therapeutic human gene is inserted into the virus (vector)
C. Cells are collected from the patients
D. Cells from the patient become genetically altered
E. Reintroduction of genetically altered cells into patient
F. Suitable virus (vector) is selected and altered
G The genetically altered cells produce the desired proteins or hormones
