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

RNA interference (RNAi) inhibits

1. DNA replication

2. Neither transcription nor translation of specific genes

3. Transcription of all genes

4. Translation of specific mRNAs

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

1. Leaf

2. Stem

3. Root

4. Flower

Which one of the following is commonly used in the transfer of foreign DNA into crop plants?

1. Trichoderma harzianum

2. Meloidogyne incognita

3. Agro bacterium tumefaciens

4. Penicillium expansum

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

(1) fungi

(2) viruses

(3) insects

(4) nematodes

Silencing of specific mRNA due to a complementary dsRNA is called mRNA silencing. Here the source of ds RNA is

Agrobacterium vectors carried nematode specific genes which is introduced into the host plant and such that it produced

RNA interference is essential for the

(1) cell proliferation

(2) cell defence

(3) cell differentiation

(4) micropropagation

From RNA interference technique
1. Toxins are made to kill soil parasites.
2. Made crops more tolerant to abiotic stresses.
3. Plants are made resistant to soil parasites.
4. Plants are developed to get the enhanced nutritional
value of food
