RNA interference (RNAi) is a natural method of cellular defense. In which of the following groups of organisms does this phenomenon naturally take place?

Options

  1. AOnly in multicellular plants and animals
  2. BIn all living organisms including prokaryotes
  3. CIn all eukaryotic organisms
  4. DOnly in prokaryotic organisms

Correct answer

C. In all eukaryotic organisms

Step-by-step solution

According to NCERT, 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. It is not naturally found as a general defense mechanism in prokaryotes, nor is it restricted only to multicellular plants and animals. Answer: In all eukaryotic organisms
