To protect tobacco plants against Meloidegyne incognita using RNAi, nematode specific genes were introduced in the plant using:

1. Transposons

2. Retrotransposons

3. Virus with RNA genome 

4. Agrobacterium

Which part of the tobacco plant is infected by Meloidegyne incognitia?

1. Leaf

2. Stem

3. Root

4. Flower

The process of RNA interference has been used in the development of plants resistant to 

(1) fungi

(2) viruses

(3) insects

(4) nematodes

What is an antisense technology?

(1) A cell displaying a foreign antigen used for synthesis of antigens.

(2) Production of somaclonal variants in tissue cultures.

(3) When a piece of RNA that is complementary in sequence is used to stop expression of a specific gene

(4) RNA polymerase producing DNA
