Which of the following is incorrect regarding RNAi effect?
(i) A nematode Meloidogyne incognita infects the roots of tabacco plants and causes a great reduction in yield.
(ii) RNA interference (RNAi) process prevent infestation of nematode to plant.
(iii) RNAi takes place in all prokaryotic organisms as a method of cellular defence.
(iv) RNAi involves silencing of a specific mRNA due to a complementary dsRNA molecule that binds to and prevents translation of the mRNA.
(v) The source of complementary RNA from an infection by viruses having DNA genomes.
(vi) The source of complementary RNA is mobile genetic elements (transposons) that replicate via a DNA intermediate.

Let's evaluate the statements:
(i) Correct - Meloidogyne incognita infects tobacco roots and reduces yield.
(ii) Correct - RNA interference (RNAi) can prevent nematode infestation.
(iii) Incorrect - RNAi occurs in eukaryotes, not in all prokaryotes.
(iv) Correct - RNAi silences specific mRNA through complementary dsRNA.
(v) Incorrect - Complementary RNA is generally produced from RNA viruses, not DNA-genome viruses.
(vi) Incorrect - Transposons that replicate via a DNA intermediate are not the source; RNAi is associated with RNA-producing elements.
Therefore, the incorrect statements are: (iii), (v), and (vi)
