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
- AOnly in multicellular plants and animals
- BIn all living organisms including prokaryotes
- CIn all eukaryotic organisms
- 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
