Read the following statements regarding RNA interference (RNAi): (A) RNAi involves silencing of a specific mRNA due to a complementary dsRNA molecule. (B) The source of this complementary RNA could be an infection by viruses having RNA genomes. (C) Transposons that replicate via an RNA intermediate can also be a source of the complementary RNA. (D) The binding of complementary dsRNA prevents the transcription of the

Step-by-step solution

Statements (A), (B), and (C) are correct. RNA interference (RNAi) takes place in all eukaryotic organisms as a method of cellular defense. It involves the silencing of a specific mRNA due to a complementary dsRNA molecule. 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. Statement (D) is incorrect because the binding of the complementary dsRNA prevents the translation (not transcription) of
