A nematode – Meloidegyne incognitia
A bacterium – Pseudomonas putida
A fungi – Trichoderma
A insect – Aphid
Correct Answer
Wrong Answer
7. Question
The problem of blindness in poor countries can be overcome by using :
Golden rice
Transgenic maize
Transgenic Tomato
Bt Brinjal
Correct Answer
Wrong Answer
8. Question
Which statement is wrong for RNA interference?
RNAi takes place in all prokaryotic organisms as a method of cellular defence.
This method involves silencing of a specific mRNA due to a complementary ds RNA.
The source of complementary ds RNA could be from a mobile genetic element (transposons) that replicate via RNA intermediate.
Agrobacterium vectors can be used to transfer gene which induce RNAi.
Correct Answer
Wrong Answer
