The correct answer is Complementary dsRNA  

Explanation:

  • Several nematodes parasitize a wide variety of plants and animals including human beings. A nematode Meloidegyne incognitia infects the roots of tobacco plants and causes a great reduction in yield.
  • A novel strategy was adopted to prevent this infestation which was based on the process of RNA interference (RNAi).
  • RNAi takes place in all eukaryotic organisms as a method of cellular defense.
  • This method involves the silencing of a specific mRNA due to a complementary dsRNA molecule that binds to and prevents translation of the mRNA (silencing).
  • The source of this complementary RNA could be from an infection by viruses having RNA genomes or mobile genetic elements (transposons) that replicate via an RNA intermediate.
