Class 12 NEET Biology Biotechnology and Its Applications

(b) : RNA interference (RNAi) is the phenomenon of inhibiting activity of a gene through production of both sense and antisense RNA. RNAi takes place in all eukaryotic organisms as a method of cellular defense. This method involves a specific m RNA silencing. It is due to a complementary dsRNA molecule which binds to and prevents translation of the m RNA causing its silencing.
