Question

Identify the wrong statements :

a) Genetic modifications in plants helped to reduce post-harvest losses
b) In Tobacco, cry genes are introduced against nematodes
c) In gene therapy, healthy genes are inserted into persons cells and tissues to treat diseases
d) Injustice, inadequate compensation, and benefit-sharing are related to molecular diagnosis

• A. a, b, c
• B. b, c, d
• C. a, b, d
• D. a, c, d

Answer 1

Answer: (B)

b, c, d

• Nematode-specific gene was introduced into tobacco plant via Agrobacterium vector. The introduced DNA produced both sense and antisense RNA which were complementary to each other and formed dsRNA. This RNA interference caused the silencing of nematode-specific mRNA and was lethal for the survival of nematode in tobacco root cells.
• Gene therapy is the treatment that is done for genetic diseases. This is the therapy that uses the genes for the treatment by replacing the defective gene.
• The gene is inserted into the person's germ cells in order to treat the problem.
• Injustice, inadequate compensation, and benefit-sharing are the terms used to express the problems related to biopiracy. It is the use of resources of the others without the proper consent of the person or the country.

So the correct answer is option B.
