Consider the following statements regarding the mechanism of pest resistance developed in tobacco plants against nematodes: A. This mechanism takes place in all eukaryotic organisms as a method of cellular defense. B. It involves the silencing of a specific mRNA due to a complementary dsRNA molecule. C. Agrobacterium vectors are used to introduce nematode-specific genes into the host plant. D. The introduced DNA prod

Step-by-step solution

Statements A, B, and C are correct. Statement A is correct because RNA interference (RNAi) takes place in all eukaryotic organisms as a method of cellular defense. Statement B is correct as the process involves the silencing of a specific mRNA due to a complementary dsRNA molecule that binds to and prevents translation of the mRNA. Statement C is correct because Agrobacterium vectors are used to introduce nematode-specific genes into the host plant. Statement D is incorrect because the introduction of DNA is design
