Read the statements and choose the correct option: Statement A : RNAi take place in all prokaryotic and eukaryotic organisms as a method of cellular defence. Statement B : RNA interference is a pretranslational process.
1 Statement A is incorrect, Statement B is correct.
2 Statement A is correct, Statement B is incorrect.
3 Both statements are correct.
4 Both statements are incorrect.
Explanation:
RNA interference (RNAi) is a process in which a specific mRNA is degraded due to the presence of a double stranded small interference RNA whose sequence is contained within the mRNA sequence. The RNAi occurs at the post transcriptional level and is triggered by short double-stranded RNA (dsRNA). It plays an important role in all eukaryotes defending cells against parasitic nucleotide sequences.

Name the organism that infects tobacco plant and decrease its yield
1 Meluidugyne incognita
2 Meloidegyne incognita
3 Meloidagyne incognita
4 Mycobacterium incognita
Explanation:
A nematode Meloidegyne incognitia infects the roots of tobacco plants and causes a great reduction in yield.

Tobacco plant resistant to a nematode have been developed by the introduction of DNA, which is produced (in the host cells) as
1 Only sense RNA
2 Both sense and antisense RNAs
3 Only antisenses RNA
4 Toxic protein
Explanation:
In RNA interference process, by using Agrobacterium vector, nematode specific genes were introduced into the host plants, which produced both sense and antisense RNAs in the host cells.
