Nematode Resistant Plants

Question 1

which nematode infects the plant roots ?

Answer 1

meloidegyne incognitia

Question 2

How can we prevent this infestation nematode?

Answer 2

by the help of RNA interference

Question 3

What happens when RNA interference takes place?

Answer 3

Gene Silencing occurs

Question 4

how does it take place?

Answer 4

this method involves silencing of a specific mRNA due to a complementary dsRNA molecule that binds to and prevents translation of mRNA.

Question 5

Which enzyme cleaves the ds RNA to make the siRNA?

Answer 5

Dicer enzyme

Question 6

The siRNA molecules formed are incorporated into a multi subunit _______?

Answer 6

RISC (RNA inducing silencing complex )

Question 7

Vector used for introducing nematode- specific genes into the host plant?

Answer 7

Vector agrobacterium

Question 8

change in golden rice due to transgenesis

Answer 8

Vitamin A and beta carotene rich

Question 9

change in bt cotton due to transgenesis

Answer 9

Pest resistance , herbicide

Question 10

change in flavr savr tomato due to transgenesis

Answer 10

gene for the production of polygalacturonase enzyme was inhibited due to which fruit remains fresh for a longer time .
